Detailed Implementation

[0027] The present invention provides a moisture-proof surveillance camera in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] like Figures 1-4 As shown, an embodiment of this utility model provides a surveillance camera with a moisture-proof function, including a camera body 1, a top cover 2 installed on the top of the camera body 1, the top cover 2 being installed on the top of the camera body 1 by a snap fastener, a lens 15 installed inside the camera body 1, and further including:

[0029] The moisture-proof mechanism 3 includes a moisture-proof box 4. An opening is provided at the top of the cover 2, and the moisture-proof box 4 is located within this opening. A mounting component 6 is provided on the top of the moisture-proof box 4 for fixing it to the cover 2. The moisture-proof box 4 is positioned above the lens 15. Small holes 14 for air circulation are provided on the side of the moisture-proof box 4. The moisture-proof box 4 is filled with desiccant, specifically silica gel granules. By placing the moisture-proof box 4 within the opening above the lens 15, the desiccant inside the moisture-proof box 4 can contact the air inside the camera body 1 through the small holes 14 on the side. Air enters the moisture-proof box 4 through the small holes 14, and the moisture in the air is absorbed by the desiccant, thereby reducing the humidity inside the camera body 1. This prevents internal moisture from causing fogging of the lens 15, ensuring the quality of the monitoring image and preventing damage to internal electrical components due to moisture. The mounting component 6 stably fixes the moisture-proof box 4, ensuring its stable position during use and its continuous moisture-proof function.

[0030] like Figure 2 and Figure 4As shown in this embodiment, the end of the desiccant box 4 is integrally formed with a widened portion 5, which is located above the lens 15. The widened portion 5 is located above the lens 15, which can expand the contact range with the air around the lens 15, so that the desiccant can more comprehensively absorb the moisture in the air near the lens 15, improve the targeting and effect of desiccant on the area around the lens 15, and further reduce the possibility of fogging of the lens 15.

[0031] like Figures 1-3 As shown in this embodiment, the mounting component 6 includes a cover plate 7 detachably connected to the top of the moisture-proof box 4. The cover plate 7 is installed on the top of the upper cover 2, and a sealing ring 8 is placed on the top of the upper cover 2. The cover plate 7 presses on the top of the sealing ring 8. The cover plate 7 is detachably connected to the top of the moisture-proof box 4, which makes it easy to remove the cover plate 7 for operation when the moisture-proof box 4 needs to be replaced. The cover plate 7 pressing on the top of the sealing ring 8 can cause the sealing ring 8 to deform and tightly fit the upper cover 2 and the cover plate 7, thereby achieving a seal at the opening of the moisture-proof box 4, preventing external moisture from seeping into the camera body 1 from the opening, and ensuring the moisture-proof effect.

[0032] like Figure 1 and Figure 3 As shown in this embodiment, several screws 12 are fixed to the top of the upper cover 2. The upper cover 2 is fitted onto the screws 12. Nuts 13 are threaded onto the screws 12. The nuts 13 press on the cover plate 7. Through the cooperation of the screws 12 and the nuts 13, the cover plate 7 can be firmly pressed onto the top of the upper cover 2, so that the cover plate 7 stably presses the sealing ring 8 to ensure the sealing effect. At the same time, the cover plate 7 can be removed by unscrewing the nuts 13. The operation is simple and convenient, which provides convenience for the disassembly and replacement of the moisture-proof box 4.

[0033] like Figure 1 and Figure 3 As shown in this embodiment, a front baffle 10 and a rear baffle 11 are fixed to the top of the cover 2. The front baffle 10 and the rear baffle 11 are respectively attached to the opposite ends of the cover plate 7. When it rains, the front baffle 10 and the rear baffle 11 can effectively block rainwater flowing down from the front and rear directions, prevent rainwater from directly contacting the sealing ring 8, prevent rainwater from eroding the sealing ring 8, extend the service life of the sealing ring 8, ensure the sealing ability of the sealing ring 8, and further ensure the moisture-proof effect.

[0034] like Figure 1 and Figure 3 As shown in this embodiment, the lengths of the front baffle 10 and the rear baffle 11 are both greater than the width of the cover plate 7. The greater lengths of the front baffle 10 and the rear baffle 11 can expand the range of rainwater blocking. Even if rainwater flows down from the edge area in the front-to-back direction, it can be effectively blocked by the front baffle 10 and the rear baffle 11, further reducing the possibility of rainwater contacting the sealing ring 8 and enhancing the protective effect on the sealing ring 8.

[0035] like Figure 1 As shown in this embodiment, the cover plate 7 has a bend 9 on the opposite side. The bend 9 is located on the side of the cover plate 7. In rainy weather, it can block rainwater flowing down from the side. It works together with the front baffle 10 and the rear baffle 11 to form an all-round rainproof structure, effectively preventing rainwater from contacting the sealing ring 8, preventing rainwater from corroding the sealing ring 8, extending the service life of the sealing ring 8, and ensuring the sealing ability of the sealing ring 8.

[0036] like Figure 3 As shown in this embodiment, the desiccant box 4 is installed at the bottom of the cover plate 7 by screws. The screws secure the desiccant box 4 to the bottom of the cover plate 7, ensuring a stable and reliable connection that prevents the desiccant box 4 from easily loosening during use. Furthermore, when it is necessary to replace the desiccant inside the desiccant box 4, the old desiccant box 4 can be removed simply by unscrewing the screws, and the new desiccant box 4 can be replaced and then secured with screws. This operation is convenient and easy to maintain.

[0037] Working principle: The desiccant box 4 in the desiccant mechanism 3 is located in the opening at the top of the cover 2 and above the lens 15. The desiccant inside can come into contact with the air inside the camera body 1 through the small hole 14 on the side. When the humidity of the air inside the camera body 1 is high, the air will enter the desiccant box 4 through the small hole 14. The moisture in the air is absorbed by the desiccant, thereby reducing the humidity of the air inside the camera body 1, preventing the lens 15 from fogging due to internal dampness, ensuring the quality of the monitoring image, and at the same time avoiding damage to the internal electrical components due to moisture.

[0038] The widened part 5, which is integrally formed at the end of the moisture-proof box 4, is located above the lens 15, which can expand the contact range with the air around the lens 15 and improve the moisture-proof targeting and effect.

[0039] The mounting component 6 is used to fix the moisture-proof box 4 to the top cover 2. The cover plate 7 is installed on the top of the moisture-proof box 4 by screws. After the screw 12 on the top of the top cover 2 passes through the cover plate 7, the nut 13 is tightened and pressed on the cover plate 7, so that the cover plate 7 presses the sealing ring 8 on the top of the top cover 2, thereby achieving the sealing and fixing of the moisture-proof box 4 at the opening and preventing external moisture from seeping in from the opening.

[0040] When it is necessary to replace the desiccant in the desiccant box 4, unscrew the nut 13 and remove the cover plate 7, then remove the screws that fix the desiccant box 4 to remove the old desiccant box 4, and then fix the new desiccant box 4 with the screws. The operation is convenient.

[0041] The front baffle 10 and rear baffle 11 on the top of the cover 2 are respectively attached to the opposite ends of the cover plate 7, and the length of both is greater than the width of the cover plate 7. The bent part 9 on the opposite side of the cover plate 7 is located on the side of the cover plate 7. The three work together. In rainy weather, the front baffle 10 and rear baffle 11 can block rainwater flowing down from the front and rear, and the bent part 9 can block rainwater flowing down from the side, effectively preventing rainwater from contacting the sealing ring 8, preventing rainwater from eroding the sealing ring 8, extending the service life of the sealing ring 8, ensuring the sealing ability of the sealing ring 8, and further ensuring the moisture-proof effect.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
