The outer ring of micro-crystal plate 3 is tightly attached in protrusion, and is screwed in protrusion by protrusion, and the lower end surface of micro-crystal plate 3 and fever
Body 2 is in contact.
No matter which kind of mounting means, it is only necessary to micro-crystal plate 3 can be mounted on the top of heater 2 and connect with heater 2
Touching that is to say that micro-crystal plate 3 can carry out hot transmitting with heater 2.
As shown in Figure 7 and Figure 8, it is equipped with the first retainer plate 13 in the upper end of outer housing 1, the lower section of the first retainer plate 13 is equipped with
First retainer plate 13 and the air being discharged at air outlet 12 can be separated, be prevented by the first insulation ring 131, the first insulation ring 131
First retainer plate 13 overheat, is equipped with the second insulation ring 311, the second insulation ring 311 can between micro-crystal plate 3 and the second retainer plate 31
To separate micro-crystal plate 3 and the first retainer plate 13, prevent the first retainer plate 13 from overheating.The outer ring of first retainer plate 13 is fixed (can
To weld or be connected by screw to) in the upper end of outer housing 1, inner ring extends to the center of gravity direction of outer housing 1, the first retainer plate
13 and second retainer plate 31 form air outlet 12, the first retainer plate 13 is horizontally disposed and inner ring is equipped with downward protrusion, second
The longitudinal cross-section of retainer plate 31 is in bent, so that the flow direction for the air that the air outlet 12 formed is discharged is obliquely (close to outer
The side of shell 1), after encountering micro-crystal plate 3 via the air obliquely that air outlet 12 is discharged, then just contacted with furnace body 9, and
Furnace body 9 carries out reheating, reaches the secondary use of resource.
In the present embodiment, air outlet 12 can be formed by the first retainer plate 13 shown in Fig. 7 and the second retainer plate 31,
The shape of the air outlet 12 is determined by the first retainer plate 13 and the second retainer plate 31, i.e. described in Fig. 7,12 section shape of air outlet
For shown in Fig. 7, the left end of air outlet 12 is vertical state, and due to the shape of the first retainer plate 13 and the second retainer plate 31, make
Air outlet 12 right end top edges have it is downwardly convex, lower edge is then in bent, thus in 1 inner cavity of outer housing
Air, air can oblique lower section discharge after the right end of air outlet 12.And finally furnace body 9 is heated.In other implementations
In example, air outlet 12 can be formed by outer housing 1 or air outlet 12 is also possible to be formed by heater 2 and outer housing 1,
In fact regardless of air outlet 12 is formed by which kind of above-mentioned mode, as long as reaching following effect: i.e. the sky of the discharge of air outlet 12
Gas and heats the furnace body 9 being placed on outer housing 1 along the inside of outer housing 1.
Be equipped at air inlet 11 lattice-shaped baffle (or lattice-shaped baffle can be cover board, have through-hole on the cover board,
Air can be allowed from passing through in through-hole and enter in the inner cavity of outer housing 1, and lattice-shaped baffle can block external roach
Dung beetle), a hoop net lattice 121 are equipped at air outlet 12, grid 121 is for stopping external cockroach to enter in the inner cavity of outer housing 1.Net
The gap in the hole between lattice 121 can according to need to be changed, and will not only interfere the discharge of 12 air of air outlet, but also
It can also prevent the pest of cockroach from entering in the inner cavity of outer housing 1.The shape of grid 121 also can according to need to be changed
Become, such as: grid 121 be it is continuous, it is continual, be also possible to discontinuous.
As shown in 7 and Fig. 8, a circle heat insulator 4 is installed on the inner wall of outer housing 1, the height of the heat insulator 4 is greater than hair
The height of hot body, heat insulator 4 can be fixed on the inner wall of outer housing 1 by way of pasting or screw connects.Due to every
The height of hot body 4 is greater than the height of heater, and therefore, the presence of heat insulator 4 can prevent the inner cavity of outer housing 1 and outside from occurring
Heat transmitting, and the heat for inner cavity of scattering and disappearing.
As shown in Figure 6 and Figure 7, (the number of LED light 5 in the present embodiment of multiple LED light 5 is installed on the inner wall of outer housing 1
Amount preferably five, in other embodiments, the quantity of LED light 5 is also possible to seven etc.), multiple LED light 5 are located at same water
In plane, and it is evenly distributed on the inner wall of outer housing 1.Multiple LED light 5 can illuminate the inner cavity of outer housing 1, can play
The effect of illumination.
When night is using the present invention outdoors, due to the dark of surrounding, multiple LED light 5 can play photograph
External furnace body 9 can be easily placed on micro-crystal plate 3 by bright effect by the illumination of multiple LED light 5.
In the present invention, air can enter in inner cavity from the air inlet 11 of electrical heating apparatus, can take away in inner cavity
Partial heat, and be discharged by air outlet 12, prevent inner cavity from overheating and being damaged, and due to the air outlet of electrical heating apparatus
The air of 12 discharges is flowed to horizontal by acute angle and towards 1 center of gravity of outer housing, and therefore, the air that air outlet 12 is discharged (has
Heat) furnace body 9 (furnace body 9 is external container) for being placed on 2 top of heater can be heated again.
The air inlet 11 and air outlet 12 that the present invention is arranged can not only play the role of heat dissipation and (mainly be to aid in inner cavity to dissipate
Heat), and the air being discharged from air outlet 12 can also again heat furnace body 9, it can be dual-purpose at one stroke.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
