Description

Technical Field

[0001] The utility model relates to the technical field of underwater electronic products, in particular to a hidden air pressure balance structure. Background Art

[0002] As we all know, outdoor electronic products, such as cameras, which are exposed to the outdoors for a long time, need to be designed with waterproof features to avoid short circuits in internal circuit components when exposed to water.

[0003] Currently, existing outdoor electronic products designed for waterproofing are generally constructed with fully enclosed structures, creating an internal space isolated from the outside world to achieve waterproofing. However, waterproof products generally require a vent in the housing to balance the internal and external air pressures. Conventional vents typically involve creating a hole directly in the housing and inserting a breathable membrane within the hole. While this design achieves both waterproofing and ventilation, for electronic products, having a hole directly in the housing can compromise the product's appearance.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a concealed air pressure balancing structure with no visible holes from the outside.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hidden air pressure balance structure, comprising a connecting rod provided on a product base and a mating hole provided on a product housing, wherein the top end of the connecting rod is provided with an external threaded surface, and the connecting rod is provided with at least one exhaust groove for transversely penetrating the external threaded surface on the external threaded surface; a port at one end of the mating hole is connected to the interior of the product and is fixedly mounted with a ring piece, an inner ring of the ring piece is provided with a breathable membrane, the breathable membrane is docked with the port of the mating hole, and a threaded joint is built into the port at the other end of the mating hole, and one end of the threaded joint is connected to the mating hole;

[0008] The connecting rod is screwed into the threaded joint by means of the external threaded surface, and a gap exists between the top end surface of the connecting rod and the bottom end of the threaded joint, so that the exhaust groove is connected to the mounting hole.

[0009] Preferably, a blocking piece is fixedly mounted on the surface of the ring piece, and at least a notch is provided on the side surface of the blocking piece, and the inner ring of the ring piece is butted against the notch.

[0010] Preferably, the shape of the notch at the joint with the inner ring of the ring piece corresponds to the inner ring of the ring piece.

[0011] Preferably, the side surface of the connecting rod is provided with at least one groove opening communicating with the exhaust groove.

[0012] Preferably, the threaded joint is a copper sleeve.

[0013] Due to the adoption of the above-mentioned scheme, the utility model sets a channel and a breathable membrane for internal and external exhaust between the connecting rod and the mounting hole, and relies on the locking of the connecting rod to cover the hole, so that the hole for exhaust is completely invisible from the outside of the product. The overall balance between the internal and external air pressure is ensured, and the hole for balancing the air pressure can be hidden, thereby ensuring the integrity of the product's appearance.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, removable connections, or integral connections. They may refer to mechanical connections or electrical connections.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0021] like Figures 1 to 4 As shown, a hidden air pressure balance structure provided in this embodiment includes a connecting rod 1 provided on a product base 100 and a matching hole 2 provided on a housing of a product 200. The top end of the connecting rod 1 is provided with an external threaded surface 3. The connecting rod 1 is provided with at least one exhaust groove 4 for transversely penetrating the external threaded surface 3. The port at one end of the matching hole 2 is communicated with the interior of the product 200 and is fixedly installed with a ring piece 5. A breathable membrane 6 is provided in the inner ring of the ring piece 5. The breathable membrane 6 is docked with the port of the matching hole 2. A threaded joint 7 is built into the port at the other end of the matching hole 2. The threaded joint 7 is a copper sleeve. One end of the threaded joint 7 is communicated with the matching hole 2.

[0022] The connecting rod 1 is screwed into the threaded joint 7 by means of the external threaded surface 3 , and a gap 300 is provided between the top surface of the connecting rod 1 and the bottom end of the threaded joint 7 , so that the exhaust groove 4 is connected to the mounting hole 2 .

[0023] The passageway for balancing internal and external air pressure in this embodiment is formed by the inner opening of the ring plate 5, the mounting hole 2, the gap 300 between the top surface of the connecting rod 1 and the bottom end of the threaded joint 7, and the exhaust groove 4. Air inside the product 200 first enters the inner opening of the ring plate 5, is filtered by the breathable membrane 6, enters the channel of the mounting hole 2, and then enters the gap 300. Because the exhaust groove 4 extends through the external threaded surface, the gap 300 is connected to the exhaust groove 4. The air inside the product 200 then enters the exhaust groove 4 until it is discharged to the outside. External air also enters the interior of the product 200 through the formed passageway, thus achieving internal and external air pressure balance. The entire passageway is hidden in the location originally used for assembly between the base 100 and the product 200, so there is no need to open additional holes in the outer shell of the product 200 itself.

[0024] Furthermore, to prevent the internal components of product 200 from obstructing the inner ring opening of ring plate 5, a baffle 8 is fixedly mounted on the surface of ring plate 5 in this embodiment. The side of baffle 8 is provided with at least one notch 9, and the inner ring of ring plate 5 is butted against notch 9. This allows baffle 8 to prevent any components from completely abutting against the inner ring opening of ring plate 5. The notch 9 on the side of baffle 8 still forms an air inlet and outlet, thus preventing blockage. Furthermore, the shape of notch 9 at the abutment with the inner ring of ring plate 5 corresponds to that of the inner ring of ring plate 5.

[0025] Furthermore, when the thread is tightened, the end face of the connecting rod 1 may directly form a tight fit with the outer shell of the product. In order to prevent the exhaust groove 4 from communicating with the outside after the tight fit, the side of the connecting rod 1 of this embodiment is provided with at least one groove opening 10 connected to the exhaust groove 4. In this way, the groove opening 10 located on the side of the connecting rod 1 can ensure communication with the outside world, so that the exhaust groove 4 can be guaranteed to be connected with the outside world regardless of whether the connecting rod 1 is tightened.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
