Abstract
The utility model relates to a microwave resonant cavity comprising a microwave resonant cavity and a light reflection surface arranged at the top surface inside the resonant cavity. The light reflection surface is provided with two microwave energy feeding openings. Two opposite sidewalls of the microwave resonant cavity are provided with a plurality of air vents. The air vents on one side are an air-inlet side. The air vents on the other one side are an air-outlet side. The high-heat radiation-type microwave resonant cavity of the utility model is simple in structure and easy to manufacture. A microwave guiding cavity and a microwave resonant cavity which are of a split structure are adopted. The microwave resonant cavity is design individually, and the microwave resonant cavity and the light reflection surface are manufactured through one-body or casting. The production, the assembly and the maintenance are provided with convenience. The microwave resonant cavity employs a one-body structure, so that heat of other parts of a microwave ultraviolet light source isolated and is prevented from entering the microwave guiding cavity, and the processing of a lot of materials with low poor resistance properties become possible. Air in the front end of the microwave resonant cavity moves in a horizontal direction, so that the cooling efficiency is raised.
Description
Technical field
The utility model relates to the microwave non-electrode light sources technical field, especially a kind of microwave cavity.
Background technology
At present, along with scientific and technical development, the production efficiencys such as mobile phone screen, automobile external part improve day by day, make the demand curing scientific and technological to optics more and more higher, it is a kind of photochemistry that ultraviolet ray (UV) is solidified, to utilize high-intensity ultraviolet ray to be irradiated, by widely used printing ink in industry, paint, solidify in addition instantaneous solidification of glue, traditional microwave non-electrode light source mainly is comprised of magnetron, microwave guide cavity, microwave cavity, electrodeless fluorescent tube, light reflection surface, micro-wave screening cover etc.Microwave guide cavity and microwave cavity are the integral type structure, light reflection surface is installed in microwave cavity, light reflection surface is the common part of microwave guide cavity and microwave cavity, have the microwave energy-feeding mouth on light reflection surface, the microwave energy-feeding mouth is for importing the microwave of microwave guide cavity in microwave cavity and excite electrodeless fluorescent tube luminous.Have ventilation hole on the outer wall of traditional microwave guide cavity, blower fan is dried from top to bottom, cause like this wind that blower fan blows into that the heat of magnetron is brought in microwave cavity, the temperature of magnetron is up to hundreds of degree centigrade, after cooling air is heated, becoming after high-temperature gas enters microwave cavity raises the microwave resonance cavity temperature, and the heat produced without motor fluorescent tube self in microwave cavity is further blowed to and treats cured article with high-temperature gas, make the temperature for the treatment of cured article raise fast, have a strong impact on the quality for the treatment of cured article of microwave cavity front, more serious meeting damages treats cured article.When the thermal endurance until cured article is poor, just can not adopt such uviol lamp, make the utilization scope greatly narrow down.
The utility model content
The technical problems to be solved in the utility model is: the microwave cavity unreasonable structure that overcomes microwave non-electrode light source in prior art makes while using temperature higher, the technical problem of cured article is treated in damage, a kind of microwave cavity is provided, improve the thermal diffusivity of microwave cavity, thereby guarantee to treat the quality of cured article.
The utility model solves the technical scheme that its technical problem adopts: a kind of microwave cavity, comprise microwave cavity and the light reflection surface that is positioned at the microwave cavity inside top surface, described light reflection surface is provided with two microwave energy-feeding mouths, described microwave cavity wherein on two relative sidewalls, offer a plurality of ventilation holes, wherein the ventilation hole of a side is inlet side, and the ventilation hole of opposite side is air side.The horizontally set ventilation hole, refrigerating gas is in transverse movement, and the heat that electrodeless fluorescent tube can not produced blows to treats cured article, avoids impact to treat the quality of cured article.
Further, for the ease of cooling air, enter in microwave cavity, the aperture that the ventilation hole of described inlet side is outer wall side is greater than the countersinking of inwall lateral aperture, and the ventilation hole of air side is straight hole.Countersinking is convenient to gas and is entered, and straight hole is convenient to Bas Discharged, reaches radiating effect preferably.
Further, for the hot-air reduced in microwave cavity enters the microwave guide cavity, described two microwave energy-feeding mouth places are provided with respectively mica sheet.Mica sheet can make microwave in the microwave guide cavity through entering in microwave cavity, and stops the hot-air in microwave cavity to enter the microwave guide cavity.
Further, described microwave cavity and light reflection surface are that integral type die casting or casting form.
The beneficial effects of the utility model are, microwave cavity of the present utility model is simple in structure, be easy to manufacture, microwave guide cavity and the microwave cavity of Split type structure have been adopted, microwave cavity designs separately, and microwave cavity and light reflection surface integrated die-casting or casting are manufactured, be convenient to produce, assemble and safeguard; Microwave cavity adopts integral structure, and the heat that has completely cut off the miscellaneous part in microwave ultraviolet source enters the microwave guide cavity, has guaranteed to treat that cured article carries out at lower temperature, thereby makes the material of the many poor heat resistance of processing become possibility; The air horizontal movement of microwave cavity front end, thus cooling effectiveness improved.
