Abstract
The utility model discloses a waterproof and breathable device for an electric horn, and aims to provide a waterproof and breathable device, which can ensure water resistance and ventilation while foreign objects on breather holes are conveniently and quickly cleaned. The waterproof and breathable device comprises an electric horn base plate; breather holes penetrating through the base plate are formed on the base plate of the electric horn; and a rotatable waterproof guard shield covering the breather holes is arranged on the outer side of the breather holes. The utility model is suitable for electric horns which are possible to become wet.
Description
Technical field
The utility model relates to a kind of electric horn, more specifically to a kind of air permeable waterproof device of electric horn.
Background technology
General electric horn does not have gas permeable devices or ventilating structure is arranged but non-watertight.The high temperature organic gas that produces in the pelvic cavity during electric horn work can't be got rid of, and can quicken the oxidation of loudspeaker contact and inner components, causes the disabler of electric horn.Ventilating structure is arranged but non-watertightly then the time may intake, thereby damage electric horn in work.
Chinese patent notification number CN200947345Y, the day for announcing is on September 12nd, 2007, name is called in " the air permeable waterproof device of electric horn of motor vehicle " discloses the scheme of opening air-vent and the air permeable waterproof device being installed on the electric horn chassis.Its structure is to open the perforation air-vent on the electric horn chassis, the air-vent upper fixed has the waterproof and breathable element, terminal base is fixed on the outside, electric horn chassis, and one side is provided with and the air-vent corresponding groove terminal base towards the chassis, thus its weak point be permanent practical after described groove may be stopped up by foreign matter and make air-vent can not breathe freely and lost efficacy.And cleaning needs dismounting terminal base, the loaded down with trivial details inconvenience of operation after stopping up.
Summary of the invention
The purpose of this utility model provides a kind of air permeable waterproof device of electric horn, when guaranteeing waterproof and breathing freely, can make the work of foreign matter on the cleaning air-vent convenient and swift.
The technical scheme that the utility model technical solution problem is adopted is as follows: electric horn air permeable waterproof device of the present utility model, comprise the electric horn chassis, described electric horn has air-vent on the chassis, and there is the waterproof guard shield described air-vent outside, and described waterproof guard shield is connected with the chassis with rotating shaft.Rotating shaft can be a screw rod, also can be one-body molded with the waterproof guard shield.Air-vent can balance loudspeaker inner and outer air pressure, makes its operate as normal, and the inner high temperature corrosion gas that produces can get rid of loudspeaker work the time.
Described waterproof guard shield is an arch, and water and air can free in and out inside and outside the waterproof guard shield, but can not directly impact air-vent, and height can not enter waterproof guard shield inside greater than the foreign matter of waterproof guard shield height.The waterproof guard shield hides in the air-vent top during electric horn work, prevents that a large amount of water from directly impacting air-vent, causes and leak.Can prevent also simultaneously that tension force stops up gas circuit on the water surface, make the airing function forfeiture.
The waterproof guard shield can cover in all air-vents after forwarding inside to fully, to inner rotary all air-vents is exposed fully.When waterproof guard shield inner product has foreign matter to stop up air-vent, can be convenient to clear up foreign matter with it to inner rotary.
Be coated with waterproof ventilative material on the described air-vent, anti-sealing and other dust foreign matters flow into, and waterproof ventilative material can be fixed or push down with coil rack with glue.Waterproof ventilative material can be that hydrophilic film also can be a waterproof breathable cloth etc.
Described air-vent effective diameter is 5mm to 10mm, too big waste waterproof ventilative material, and can reduce the impact resistance of device, too little then blocked easily.1 above air-vent can be arranged to strengthen gas permeability.Air-vent can be circle, rectangle or other shapes.
The utility model beneficial effect against existing technologies is, because the waterproof guard shield can independently rotate, when guaranteeing the air permeable waterproof effect, also can make the work of cleaning air-vent obtain simplifying, and avoids dismounting, raises the efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1, electric horn chassis, 2, rotating shaft, 3, the waterproof guard shield, 4, air-vent, 5, hydrophilic film.
Embodiment
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment:
Embodiment: a kind of electric horn air permeable waterproof device (referring to Fig. 1), the circular air-vent 4 on the perforation chassis that to have 1 aperture be 7mm, 1 place of keeping to the side on the chassis.Be fixed with hydrophilic film 5 on the air-vent 4.1 outside, chassis is connected with waterproof guard shield 3 with rotating shaft 2, and rotating shaft and waterproof guard shield are one-body molded.Waterproof guard shield 3 is an arch, can independently rotate around rotating shaft, can hide or expose air-vent 4 fully.Waterproof guard shield 3 inwardly goes to the position that air-vent 4 is covered fully during electric horn work, prevents that a large amount of water from directly impacting air-vent 4, causes and leaks, and also can prevent that tension force stops up gas circuit on the water surface simultaneously, makes the airing function forfeiture.When foreign matter stops up air-vent 4, waterproof guard shield 3 outwards rotated to expose air-vent 4 fully, can clear up foreign matter this moment easily.
Claims (7)
1. an electric horn air permeable waterproof device comprises the electric horn chassis, it is characterized in that, has the air-vent that connects the chassis on the described electric horn chassis, and there is the waterproof guard shield that covers air-vent described air-vent outside.
