Description

Technical Field

[0001] The utility model relates to the technical field of air permeable caps, in particular to a push-type air permeable cap. Background Art

[0002] Push-type vent caps are installed on many devices. For example, push-type vent caps are installed on lamps and other equipment. They are an important component to achieve internal pressure balance and waterproofing of the equipment. The high-pressure gas generated by the heat when the equipment is working can be discharged through the push-type vent cap to balance the pressure inside and outside the equipment. When the internal pressure of the equipment is negative, the pressure can be balanced by pressing the vent cap to inlet air, effectively isolating gaseous moisture from entering the equipment and reducing the probability of water mist and water droplets forming inside the equipment. Figure 5 As shown, the existing push-type breathable cap has an unreasonable structure, and the inner core is made of TPE material, the actual maximum high temperature resistance of this material does not exceed 80 degrees, and the anti-aging shrinkage is poor; the applicability is poor.

[0022] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Reference Figures 1 to 4The utility model provides a push-type breathable cap, comprising a circular breathable cap inner core 2, a breathable cap outer shell 1 is provided on the outer surface of the breathable cap inner core 2, the breathable cap outer shell 1 comprises an outer ring 11 formed by integral processing and a top plate 12 arranged on the top of the outer ring 11, the outer ring 11 is sleeved on the breathable cap inner core 2, a breathable membrane 7 is provided between the upper end surface of the breathable cap inner core 2 and the lower end surface of the top plate 12, the breathable membrane 7 is welded on the top plate 12, and a breathable hole 3 is provided on the top plate 12 above the breathable membrane 7.

[0024] The breathable membrane 7 of the present technical solution is ultrasonically welded to the top plate 12. The structure of the present technical solution is simple; it only needs to press the product into the reserved installation position of the equipment. The internal air pressure balance and waterproofing of the equipment are achieved. Figure 4-5 As shown, the technical solution is to ventilate upward through the middle of the breathable membrane shell 1, which has a better effect than the prior art of ventilating toward the lower end of the breathable cap shell 1.

[0025] The technical solution is provided with a vent hole 3 on the outer shell 1 of the vent cap, which is simple to install, simple in structure, and easy to produce and process; the material is applicable to a wider range of environments and has better temperature resistance. During use, the high-pressure gas generated by the heat generated when the equipment is working can be discharged through the push-type vent cap to balance the pressure inside and outside the equipment. When the internal pressure is negative, the air can be introduced into the vent cap to balance the pressure, effectively isolating gaseous moisture from entering the interior of the equipment and reducing the probability of water mist and water droplets forming inside the equipment.

[0026] For example, in some embodiments, there are multiple air holes 3. There are seven air holes 3, one of which is located at the center of the top plate 12, and the other six air holes are arranged in a circle with the air hole at the center of the top plate as the center. This arrangement makes the air permeability more uniform and better.

[0027] For example, in some embodiments, the material of the inner core 2 of the breathable cap is silica gel, which is more heat-resistant, has better anti-aging shrinkage and better applicability than the existing TPE material.

[0028] For example, in some embodiments, the breathable cap shell 1 is made of hard plastic.

[0029] For example, in some embodiments, an annular groove 8 is provided on the outer surface of the breathable cap inner core 2, and a snap ring 4 is provided at the inner lower end of the outer ring 11 to engage with the annular groove 8. This facilitates the connection between the breathable cap outer shell 1 and the breathable cap inner core 2.

[0030] For example, in some embodiments, the inner core 2 of the air permeable cap is a tapered hole 5 that is smaller at the top and larger at the bottom, and a plurality of annular protrusions 6 are provided in the tapered hole 5. This facilitates connection with the connection part of the device to be connected.

[0031] In summary, the utility model provides ventilation holes on the outer shell of the ventilation cap, which is simple to install, simple in structure, and easy to produce and process; the material is more applicable to a wider range of environments and has better temperature resistance.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
