Description

Technical Field

[0001] The utility model belongs to the technical field of vent valves, in particular to a waterproof vent valve connection structure for lamps and instruments. Background Art

[0002] To prevent water from entering lamps and instruments during use, especially those used outdoors and exposed, such as the lights and instruments on two-wheeled and three-wheeled electric vehicles, most of the lamp and instrument shells are fully sealed and waterproof using a gluing process. After the lamps and instruments generate heat, the heat is not circulated through the shell, resulting in an increase in the air pressure inside the lamps and instruments, which may cause the lamp and instrument shells to bulge, causing the glue to expand and eventually leaking.

[0003] The current solution involves creating a through hole in the housing of a lamp or instrument and either directly attaching a waterproof breathable membrane to the hole or adding a silicone sleeve over the membrane. Both solutions carry the risk of falling due to aging during subsequent use, potentially leading to water ingress into the lamp or instrument. Utility Model Content

[0004] In view of this, the present invention aims to overcome the above-mentioned deficiencies in the prior art and proposes a waterproof and breathable valve connection structure for lamps and instruments.

A U-shaped third gap is provided between the inner and outer side walls and the bottom side wall of the plug-in portion and the inner wall of the annular groove. The first gap, the second gap and the third gap are connected, and the third gap is connected to the outside world at the outer side wall of the plug-in portion.

[0008] Furthermore, a plurality of vertically arranged fixing ridges are evenly provided on the inner and outer side walls of the plug-in portion, and the plug-in portion is plugged into the annular groove through interference fit between the fixing ridges and the annular groove.

[0009] Furthermore, two symmetrically arranged abutting portions are fixedly connected to the bottom of the end cover portion corresponding to the waterproof breathable membrane, and the abutting portions abut against the upper side of the waterproof breathable membrane.

[0010] Furthermore, there are two plug-in parts, which are arc-shaped and symmetrically arranged at the bottom of the end cover part.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] As shown in the figure, a waterproof breathable valve connection structure for lamps and instruments includes a valve body 1, a waterproof breathable membrane 2 and a base 3. The base 3 includes an inner ring 32 and an outer ring 31 arranged coaxially. A seal is set between the bottom ends of the inner ring 32 and the outer ring 31. An annular groove 33 with a U-shaped cross section is formed between the inner ring 32, the outer ring 31 and the seal. A connecting platform 34 is provided on the inner side wall of the inner ring 32. A breathable hole 35 is opened in the middle of the connecting platform 34. The waterproof breathable membrane 2 is fixed to the upper side of the connecting platform 34 and covers the breathable hole 35. The valve body 1 includes an end The cover portion 11 and the plug-in portion 12 disposed at the bottom of the end cover portion 11 are fixedly inserted into the annular groove 33. The end cover portion 11 is located above the waterproof breathable membrane 2. A first gap 4 is defined between the end cover portion 11 and the waterproof breathable membrane 2, and a second gap 5 is defined between the end cover portion 11 and the inner ring 32. A U-shaped third gap 6 is defined between the inner and outer side walls and the bottom side wall of the plug-in portion 12 and the inner wall of the annular groove 33. The first gap 4, the second gap 5, and the third gap 6 are interconnected, and the third gap 6 is connected to the outside world at the outer wall of the plug-in portion 12. In this embodiment, the valve body 1 is plugged and fastened into the annular groove 33 of the base body 3, shielding the waterproof breathable membrane 2, effectively extending the service life of the waterproof breathable membrane 2. At the same time, air circulates through the gaps between the valve body 1, the waterproof breathable membrane 2, and the annular groove 33. This structure, when used in lamps and instruments, effectively dissipates heat, balances the air pressure inside the housing, and effectively waterproofs the interior of the housing.

[0027] A plurality of vertically arranged fixing ridges 15 are evenly provided on both inner and outer side walls of the plug-in portion 12 . The plug-in portion 12 is inserted into the annular groove 33 through interference fit between the fixing ridges 15 and the annular groove 33 .

[0028] Two symmetrically arranged abutting portions 14 are fixedly connected to the bottom of the end cover portion 11 corresponding to the waterproof breathable membrane 2. The abutting portions 14 abut against the upper side of the waterproof breathable membrane 2 to further strengthen the fixation of the waterproof breathable membrane 2 and prevent the waterproof breathable membrane 2 from falling off from the connecting platform 34.

[0029] There are two plug-in parts 12, and they are arc-shaped structures, symmetrically arranged at the bottom of the end cover part 11, and a reinforcing rib 13 is connected between the middle of each end of the two plug-in parts 12. The bottom of the reinforcing rib 13 is located higher than the bottom of the plug-in part 12, and the thickness of the reinforcing rib 13 is less than the thickness of the plug-in part 12. Here, since the valve body 1 is an integrated injection molding structure, the provision of the reinforcing rib 13 can effectively enhance the strength of the valve body 1. On the other hand, the space of the third gap 6 near the reinforcing rib 13 is increased, which effectively increases the ventilation volume, that is, increases the air flowability, improves the heat dissipation efficiency, and meets the needs of products with large and fast heat generation.

[0030] An L-shaped stop groove 36 is opened circumferentially at the top of the inner wall of the outer ring 31, the edge of the end cover 11 is embedded in the stop groove 36, and the bottom is against the bottom side wall of the stop groove 36, and a groove 37 connected to the stop groove 36 is opened inward at the top of the outer ring 31 corresponding to the reinforcing rib 13, and the bottom end of the groove 37 is located below the stop groove 36. First, it will not cause constraints to the valve body 1 when installing the valve body 1. Second, the valve body 1 can be easily disassembled through the groove 37. Third, the gas flow space near the reinforcing rib 13 is further increased, thereby increasing the heat dissipation.

[0031] In this embodiment, the base 3 is also an integral injection-molded structure, with the top of the outer ring 31 extending circumferentially outward to form a complete base 3, which is connected to the cover of the lamp or instrument to form a complete shell for use. When in use, the outer ring 31 and the inner ring 32 are located inside the shell of the lamp or instrument, and the end cover 11 of the valve body 1 is exposed on the surface of the shell, thereby achieving heat dissipation and ventilation inside the lamp or instrument.

[0032] The working process of this embodiment is as follows:

[0033] The heat generated by the lamp or instrument during operation flows outward with the air flow through the waterproof breathable membrane 2, and exchanges heat with the outside air through the first gap 4, the second gap 5, and the third gap 6, thereby realizing the heat dissipation function and achieving the effect of balancing the internal and external air pressure. The waterproof breathable membrane 2 also waterproofs the interior of the shell.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
