As it is shown in figure 5, be provided with at air inlet 11 cellular grid catch (or cellular grid catch can be cover plate,
There is through hole on this cover plate, air can be allowed to pass through from through hole and enter in the inner chamber of shell body 1, and cellular grid catch can
To block the insecticide (general insecticide such as: Blatta seu periplaneta etc.) of outside, being provided with hoop net lattice 121 at air outlet 12, grid 121 is used for hindering
Gear external insect enters in the inner chamber of shell body 1.The space in the hole between grid 121 can as desired to be changed,
Not only will not hinder the discharge of air outlet 12 air, but also be possible to prevent insecticide to enter in the inner chamber of shell body 1.Grid
The shape of 121 can also be as desired to be changed, such as: grid 121 can be discontinuous as shown in Figure 5, it is also possible to
Be as shown in Figure 10, above continuous print, have multiple aperture, facilitate at air outlet distinguished and admirable go out.
As shown in 7 and Fig. 8, being provided with ring one and enclose insulator 4 on the inwall of shell body 1, the height of this insulator 4 is more than
The height of heater, insulator 4 by pasting or can be fixed on the inwall of shell body 1 by the way of screw connection.Due to
The height of insulator 4 is more than the height of heater, and therefore, the existence of insulator 4 is possible to prevent the inner chamber of shell body 1 to send out with outside
Heat is transmitted, and the heat of the inner chamber that scatters and disappears.
As shown in Figure 6 and Figure 7, the inwall of shell body 1 is provided with the multiple LED 5 (number of LED 5 in the present embodiment
Amount is preferably three, and in other embodiments, the quantity of LED 5 can also be less than three or more than three), multiple
LED 5 is positioned at electrical heating utensil cavity, and is evenly distributed on inwall and the circuit board of shell body 1.Multiple LED 5 are permissible
The inner chamber of shell body 1 is illuminated, the effect of illumination can be played.Meanwhile, the pattern of shell body 1 can be formed by multiple LED 5
The aesthetic of decoration.
When night uses the present invention out of doors, due to the dark of surrounding, the most multiple LED 5 can play photograph
Outside vessel 9, by the illumination of multiple LED 5, can be placed on micro-crystal plate 3 by bright effect easily.
When night uses the present invention out of doors, due to the dark of surrounding, the most multiple LED 5 can play photograph
Outside vessel 9, by the illumination of multiple LED 5, can be placed on micro-crystal plate 3 by bright effect easily.
In the present invention, air can enter into inner chamber from the air inlet 11 of electrical heating utensil, can take away in inner chamber
Partial heat, and discharged by air outlet 12, prevent inner chamber overheated and damaged, and due to air outlet 12 row of electrical heating utensil
The air flow gone out is horizontal by acute angle and towards shell body 1 center of gravity, therefore, and the air (with heat) that air outlet 12 is discharged
Again the vessel 9 (vessel 9 are external container) being placed on above heater 2 can be heated.
The air inlet 11 of present invention setting and air outlet 12 are possible not only to play the effect of heat radiation and (mainly help inner chamber to dissipate
Heat), and vessel 9 can also be heated by air again that discharge from air outlet 12, can be the most dual-purpose.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, it is also possible to making some deformation and improvement, these broadly fall into the protection model of the present invention
Enclose.
