[0055] In the related art, heating the samples in the tray by means of axial rotation can improve the heating uniformity. However, during heating, the tray cannot rotate radially, which affects the heating efficiency in the effective space.

[0056] To solve the problems in the related art to a certain extent, the embodiments of the present application provide an electric heating box. By setting a meridional rotation assembly with a wind-driven plate on it, when blowing air, the wind can drive the wind-driven plate, causing the wind-driven plate to drive the meridional rotation assembly to rotate, and the meridional rotation assembly drives the tray above to rotate radially, enabling the samples in the tray to have more uniform heat exchange in the space, achieving the effects of improving the heating efficiency and further enhancing the heating uniformity.

[0057] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0058] Combined Figures 1-6 , the embodiments of the present application provide an electric heating box, including an electric heating box 10; the electric heating box 10 includes: an outer box body 11; a heating rod 12, arranged on the inner side wall of the outer box body 11

[0059] The electric heating box 10 is composed of the outer box body 11 and the heating rod 12. When heating, the internal space of the outer box body 11 is heated by the heating rod 12;

[0060] A blowing assembly 20 is installed on the outer side wall of the electric heating box 10. The blowing assembly 20 includes: a blowing fan 21, installed on the outer side wall of the outer box body 11; a jet head 22, arranged at the air outlet end of the outer box body 11, with one end connected to the air outlet end of the blowing fan 21; a circulation pipeline 23, arranged at the air inlet end of the blowing fan 21; an air inlet hood 24, installed at the air extraction end of the outer box body 11;

[0061] When working, by starting the blowing fan 21, the blowing fan 21 pumps the hot air in the bottom space of the outer box body 11 into the jet head 22 through the circulation pipeline 23 and the air inlet hood 24, and then the high-pressure and high-temperature gas is ejected from the jet head 22 to complete the hot air circulation in the box body space;

[0062] An axial rotation assembly 30 is installed inside the electric heating box 10. The axial rotation assembly 30 includes: a driving motor 31, installed on the outer side wall of the outer box body 11; bearing seats 32, symmetrically arranged on the inner side wall of the outer box body 11; a rotating shaft 33, rotatably connected to one end of the bearing seat 32, with one end connected to the output shaft of the driving motor 31; a rotating sleeve 34, arranged on the outer side wall of the rotating shaft 33; limiting strips 35, symmetrically arranged on the outer side wall of the rotating shaft 33; a limiting groove 36, opened on the inner side wall of the rotating sleeve 34, and slidably connected to the limiting strips 35;

[0063] When heating the sample, by starting the drive motor 31, the drive motor 31 drives the rotating shaft 33 to rotate, the rotating shaft 33 drives the outer rotating sleeve 34 to rotate, the rotating sleeve 34 drives the trays 45 symmetrically arranged on the outer side wall to rotate axially, so that the samples in the trays 45 can be heated evenly. In addition, by setting the limit strip 35 and the limit groove 36, the limit groove 36 and the limit strip 35 cooperate to axially limit the rotating sleeve 34, preventing the rotating sleeve 34 from sliding axially on the rotating shaft 33. When not in use, the rotating sleeve 34 can be slid out by lateral sliding;

[0064] Radial rotating components 40 are symmetrically arranged on the outer side wall of the rotating sleeve 34.

[0065] While the tray 45 rotates axially, since the jet head 22 jets high-pressure and high-temperature gas, the high-pressure and high-temperature gas drives the rotating plate 41 to rotate through the wind-driven plate 50, so that the tray 45 on the rotating plate 41 can rotate radially, and thus the samples in the tray can have more uniform heat exchange in the space, achieving the effects of improving the heating efficiency and further improving the heating uniformity.

[0066] In some embodiments, the jet head 22 has a horn-shaped structure. The horn-shaped jet head 22 can increase the width of the ejected gas and improve the efficiency of driving the wind-driven plate 50.

[0067] In some embodiments, a plurality of ventilation holes are formed in the outer side wall of the tray 45. By setting the ventilation holes, the heat exchange efficiency between the hot air and the samples in the tray 45 is improved.

[0068] In some embodiments, there are four wind-driven plates 50 in total. The four wind-driven plates 50 are respectively arranged obliquely at an angle of thirty degrees on the top of the rotating plate 41. By setting the four wind-driven plates 50 and arranging them staggered at an angle of thirty degrees, the efficiency of wind driving can be further improved.
