Description

Breathable waterproof member for steam locomotive lamps

This creation is about a breathable waterproof member.

In general, an electronic device or a mechanical device requires a good ventilation effect to maintain its normal operation. However, once a structure such as a vent hole is provided, external dust or moisture may easily intrude into the interior of the device, causing damage to the device or Short life.

Therefore, it is common to block the water vapor or dust in the vent hole by a membrane body which is only allowed to pass through the gas and cannot pass through the liquid or the solid. However, the membrane body is easy to adsorb moisture and dust and is clogged, the gas permeable effect is not good, and the directly exposed film The body is easily damaged by external forces, and it is necessary to improve.

The main purpose of this creation is to provide a breathable and waterproof component for the locomotive of a motorcycle, which can protect the mechanical or electronic device from moisture intrusion and maintain a good ventilation effect.

In order to achieve the above object, the present invention provides a breathable waterproof member for a motorcycle locomotive, comprising a casing, a cylinder and a waterproof gas permeable membrane.

The outer casing has a ring shape and a bottom surface, and the ring wall and the bottom surface surround an accommodating space. The ring wall is radially protruded from an end of the bottom surface to provide a positioning structure, and the bottom surface is provided with at least one pad. a high structure; the tubular member is made of a material having elasticity and includes an inner cylinder and an outer cylinder, wherein the inner cylinder is disposed in the outer cylinder and is connected to the outer cylinder by a plurality of spaced connection portions, An air passage is defined between the adjacent connecting portion, the inner cylinder and the outer cylinder, and the air passage extends axially along one of the tubular members, and one end of the inner cylinder is a set of joints, and the inner cylinder is axially Extending the first-class track, the opposite end of the set of the connecting portion is received in the receiving space of the outer casing and abuts the high-rise structure, so that the flow channel can pass through the space between the high-rise structure and the The air passage is connected, the tubular member is blocked by the positioning structure and cannot freely leave the outer casing; the waterproof gas permeable membrane is disposed at one end of the inner cylinder relative to the assembly portion, and gas can enter the flow passage through the waterproof gas permeable membrane. However, liquid cannot enter the flow path through the waterproof gas permeable membrane.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIG. 1 to FIG. 7 , the present invention provides a breathable waterproof member for a motorcycle locomotive, comprising a casing 10 , a tubular member 20 and a waterproof gas permeable membrane 30 .

The outer casing 10 has a ring-shaped wall 11 and a bottom surface 12. The ring wall 11 and the bottom surface 12 define an accommodating space 13 . The ring wall 11 is radially protruded from an end of the bottom surface 12 to form a positioning structure. The bottom surface is provided with at least one pad structure 14; the tube member 20 is made of an elastic material (for example, plastic) and includes an inner tube 21 and an outer tube 22, and the inner tube 21 is disposed on the outer tube The connecting portion 23 provided at a plurality of intervals is connected to the outer tube 22, and any two adjacent connecting portions 23, the inner tube 21 and the outer tube 22 define an air passage 24, the air passage 24 is Extending along one of the tubular members 20, one end of the inner cylinder 21 is a set of joints 211. The inner cylinder 21 extends axially with a first-stage passage 212. The tubular member 20 has an opposite end of the joint portion 211. It is disposed in the accommodating space 13 of the outer casing 10 and abuts the height-adjusting structure 14 so that the flow channel 212 can communicate with the air passages 24 via the space between the height-adjusting structures 14, and the cylindrical member 20 is positioned The structure 15 is blocked from being free to leave the outer casing 10; the waterproof gas permeable membrane 30 is disposed at one end of the inner cylinder 21 with respect to the assembly portion 211, and the gas can pass through the Water enters the gas permeable membrane 30 and flow passage 212, but not through the liquid waterproof membrane 30 and into the flow passage 212.

In this embodiment, the positioning structure 15 is a ring edge, and the ring edge is radially protruded and wound around the axial direction of the outer casing 10. The height structure 14 is a stepped portion formed on the ring wall. 11 and the bottom surface 12 at a boundary around the axial direction of the outer casing 10, preferably, the inner diameter of the inner surface of the step portion is larger than the outer diameter of the inner cylinder 21 but smaller than the outer diameter of the outer cylinder 22 The outer diameter of the outer cylinder 22 is equal to or slightly larger than the inner diameter of the outer casing 10. Since the tubular member 20 is made of a resilient material, the tubular member 20 can be tightly inserted into the outer casing 10 without being easily detached; The inner cylinder 21 has one end of the assembly portion 211 protruding from the outer cylinder 22, and the assembly portion 211 is located outside the outer cylinder 22; in addition, preferably, the cylinder member 20 includes three connections. The portion 23 and the third air passage 24 have a circumferential length of each of the connecting portions 23 smaller than a circumferential length of each of the air passages 24.

In actual use, the assembly portion 211 is inserted into the joint of a device 40. The inside of the device 40 and the outside of the device communicate with each other via the flow passage 212 and the accommodating space 13 with the air passages 24, but the flow passage 212 is provided. With the waterproof gas permeable membrane 30, only gas can move between the inside of the device 40 and the outside, and the liquid cannot enter the inside of the device 40 from the outside. Therefore, the creation can achieve both waterproof and breathable effects.

It is to be noted that the cylindrical member 20 completely contacts the inner surface of the annular wall 11 of the outer casing 10 with the outer peripheral surface of the outer cylinder 22, and therefore, can provide a large frictional force, so that the cylindrical member 20 is positioned inside the outer casing 10, and the outer casing 10 is not easy to fall off from the cylinder 20, ensuring the use effect.

In summary, the creation achieves waterproof and breathable effects of electronic or mechanical devices by extremely simple structure and assembly steps, and the waterproof and breathable membrane is protected by the outer casing, and has excellent durability and great progress.
