A kind of waveguide for microwave generator
Technical field
The present invention relates to a kind of Arborescence waveguide tube, belong to the optimisation technique of waveguide.
Background technology
The microwave transmission that the effect of waveguide mainly produces microwave generator is to working space, to the thing of working space
Product are handled.Because the transmission characteristic of microwave is linear, so, in order that the microwave into working space can be abundant
Ground acts on article, therefore, in actual application, commonly uses four kinds of modes to make microwave more uniformly act on article:One is
Microwave is reflected using the inwall of working space, microwave is irradiated from all directions to article;Two be increase
Wave apparatus is stirred, the microwave that waveguide is spread out of is reflected, changes the transmission direction of microwave, microwave is sufficiently irradiated with article
On;Three be to rotate article, and such as micro-wave oven is rotated frequently with rotating disk by article;Four be using article movement by the way of, such as it is right
The microwave equipment of sterilization is dried in timber, food, by the mechanical movement of conveyer belt come transporting articles, in being transmitted across for article
Cheng Zhong, realizes irradiation of the microwave to article.
But aforesaid way complicated in mechanical structure, also, can not be as needed, different are sent to the different parts of an article
The microwave energy of intensity.
It is, thus, sought for it is simple in construction, easily realize, and varying strength can be conveyed to the different parts of article
The microwave export technique of microwave energy.
The content of the invention
The purpose of the present invention is:A kind of Arborescence waveguide tube is provided, is not only simple in structure, is easily realized, additionally it is possible to article
Different parts conveying varying strength microwave energy microwave export technique.
The technical scheme is that:A kind of waveguide for microwave generator, is mainly sent out by main waveguide 1 and microwave
Raw device 4 is constituted, and main waveguide 1 includes the trunk portion for the leader and endcapped being connected with microwave generator 4;In main ripple
The trunk portion of conduit 1 is provided with the partial wave conduit 2 of more than one endcapped;In the trunk portion and partial wave conduit of main waveguide
Wall be provided with more than one microwave delivery outlet 3;The microwave that microwave generator 4 is produced enters and its close-connected main waveguide
In pipe 1, by the refraction action of the main inwall of waveguide 1, a part is projected from the microwave delivery outlet being located on main waveguide, separately had
A part of microwave enters in partial wave conduit 2, is then reflected in partial wave conduit 2, and microwave runs into microwave delivery outlet 3 will be to
It is outer to project;The shape of microwave delivery outlet is circular or rectangular or rhombus or polygon.
Quantity, density, direction, aperture and the shape of microwave delivery outlet are set on main waveguide and partial wave conduit, made micro-
Ripple is projected in the way of setting to all directions.
The leader of described main waveguide 1 is tubaeform, and the position diameter being connected with trunk portion is maximum.
The main inwall of waveguide 1 be provided with reflector plate.
Reflector plate is provided with the inwall of partial wave conduit 2.
Beneficial effect
1st, main waveguide includes the trunk portion of leader and endcapped, and one is provided with the trunk portion of main waveguide
The partial wave conduit of individual above endcapped, can set the number of microwave delivery outlet on main waveguide and partial wave conduit as needed
Amount, density, direction, aperture and shape, make microwave be projected in the way of setting to all directions, and being truly realized can be to article
Different parts convey the microwave energy of varying strength.
Brief description of the drawings
Fig. 1 is the main structure diagram of the present invention.
Embodiment
As shown in figure 1, a kind of waveguide for microwave generator, mainly by 4 groups of main waveguide 1 and microwave generator
Into main waveguide 1 includes the trunk portion for the leader and endcapped being connected with microwave generator 4;In main waveguide 1
Trunk portion is provided with the partial wave conduit 2 of more than one endcapped;In the trunk portion of main waveguide and the wall of partial wave conduit
Provided with more than one microwave delivery outlet 3;Microwave generator 4 produce microwave enter with its close-connected main waveguide 1,
By the refraction action of the main inwall of waveguide 1, a part is projected from the microwave delivery outlet being located on main waveguide, it is another some
Microwave enters in partial wave conduit 2, is then reflected in partial wave conduit 2, microwave, which runs into microwave delivery outlet 3, outwards to be penetrated
Go out.
In actual application process, multiple microwaves can be set to export on main waveguide and partial wave conduit as needed
Hole, by setting microwave delivery outlet in diverse location, allows microwave to be transmitted to different directions;By setting microwave delivery outlet
Aperture, density, realize the microwave that varying strength is exported to the diverse location of article.Microwave hair is used for using the present invention
The waveguide of raw device, can set the quantity, density, court of microwave delivery outlet on main waveguide and partial wave conduit as needed
To, aperture and shape, microwave is set to be projected in the way of setting to all directions, being truly realized can be defeated to the different parts of article
Send the microwave energy of varying strength.
The leader of described main waveguide 1 is tubaeform, and the position bore being connected with trunk portion is maximum.
Reflector plate is provided with the main inwall of waveguide 1, to help the position that microwave directive needs microwave to export.
Reflector plate is provided with the inwall of partial wave conduit 2, to help the position that microwave directive needs microwave to export.
The shape of microwave delivery outlet can freely be set, you can be it is circular, rectangular, rhombus or
Polygon.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, and should also belong to the guarantor of the present invention
Protect category.
