Abstract
A lighting device for microwave vacuum drying equipment adopts the structure that a plurality of small holes are formed in the proper positions of a box body of the microwave vacuum drying equipment; a base is welded in the positions where the small holes are formed; the small holes are in the range of an inner hole of the base; a lower seal ring, a piece of glass, an upper seal ring and a clamping ring are sequentially installed on the base; the clamping ring is fixed on the base through bolts; the lighting device is installed on the clamping ring; the clamping ring is used for compressing the lower seal ring, the piece of glass and the upper seal ring, so as to achieve that the light can pass through the piece of glass and the small holes to enter the equipment, without air leakage and leakage of microwave energy, as a result, more light can enter the equipment.
Description
Technical field
The utility model relates to a kind of micro-wave vacuum equipment lighting device, can external lights be input to device interior, the material situation of being convenient to see drying.
Background technology
At present, for solving the micro-wave vacuum equipment lighting problem, prevent that microwave energy from leaking, can only adopt aperture input light, because hole diameter is limited, it is little to illuminate scope, is difficult to clear view to the inner dried material situation of skinny device.
Summary of the invention
In order to overcome existing micro-wave vacuum equipment lighting problem; The utility model provides a kind of micro-wave vacuum equipment lighting device; Form by base, trim ring, bolt, lighting device, last sealing ring, glass, lower seal, casing; It is big that this micro-wave vacuum equipment lighting device not only illuminates scope, and can not produce the microwave energy leakage.
The utility model solves the technical scheme that its technical problem adopted: utilize microwave energy not pass the principle of aperture; Bore some apertures in micro-wave vacuum equipment casing appropriate location, base is welded on the position that is drilled with aperture, aperture is in base endoporus scope; Lower seal, glass are housed on the base successively, go up sealing ring, trim ring; Be fixed by bolts on the trim ring on the base, lighting device is installed on the trim ring, lower seal, glass, last sealing ring are compressed through trim ring; Reach that light passes glass and aperture enters in the equipment, and can not cause gas leakage and microwave energy leakage.
The beneficial effect of the utility model is, is drilled with some apertures and can gets into more light in equipment, prevents microwave energy simultaneously to external leakage, realizes that more light access arrangements are inner.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is micro-wave vacuum equipment illuminator structure figure
Fig. 2 is the boring instance graph
Fig. 3 is base figure
Fig. 4 is trim ring figure
Among Fig. 1, base (1), trim ring (2), bolt (3), lighting device (4), last sealing ring (5), glass (6), lower seal (7), casing (8).
The specific embodiment
Among Fig. 1, be micro-wave vacuum equipment lighting device overall structure, it is characterized in that: base (1) is processed with metal, and is cylindrical; There is a hole centre, and a step cutting pattern is arranged on the hole, and the plurality of fixed screw is arranged above, and trim ring (2) is processed with metal; One step is arranged at the circular slab bottom, is drilled with above and the supporting hole of base (1), and bolt (3) is a standard component; It is supporting with base (1) screw to pass trim ring (2), and lighting device (4) is made up of complexes that market is buied, and last sealing ring (5) is processed with rubber; Can adopt standard component, glass (6) is processed circle with safety glass; Lower seal (7) is processed with rubber, can adopt standard component, and casing (8) processes with metallic plate.Base (1) is welded on casing (8) and is drilled with on the position like dry hole; Load sealing ring (7), glass (6) on the base (1) successively, go up sealing ring (5), trim ring (2); Bolt (3) passes the hole on the trim ring (2); Cooperate with base (1) screw, thereby compress sealing ring (5), glass (6) and lower seal (7) with trim ring (2).
Among Fig. 2, show casing boring sketch map, for the A among Fig. 1 to figure.
Among Fig. 3, the demonstration base is analysed and observe and vertical view.
Among Fig. 4, the demonstration trim ring is analysed and observe and vertical view.
