[0022] Specifically, Figure 2As shown, the heating rod 7 is provided with a roller 8 and a heat-insulating roller seat 9 for mounting the roller 8. The roller 8 is hinged on the heat-insulating roller seat 9 through a heat-conducting shaft 10. The heat-conducting shaft 10 is electrically connected to the electric heating device. The end of the heating rod 7 facing away from the heat-conducting plate 6 is the bottom end of the heating rod 7. When the roller 8 is not in contact with the heat-conducting plate 6, the distance between the top end of the roller 8 and the bottom end of the heating rod 7 is greater than the distance between the bottom end of the heat-conducting plate 6 and the bottom end of the heating rod 7.

Figure 1 As shown, a moving groove 13 is provided on the mounting plate 12 for allowing the heating rod 7 to move along a direction perpendicular to the extending direction of the heating rod 7 .

[0024] Specifically, Figure 3 As shown, there are three heat conducting sheets 6, and the end of the middle heat conducting sheet 6 away from the mounting plate 12 is connected to a heat transfer plate 14 spanning all the heat conducting sheets 6. When the roller 8 is not in contact with the heat conducting sheet 6 connected with the heat transfer plate 14, the heat transfer plate 14 is separated from the heat conducting sheet 6 not connected with the heat transfer plate 14. When the roller 8 is in contact with the heat conducting sheet 6 connected with the heat transfer plate 14, the heat transfer plate 14 is in contact with all the heat conducting sheets 6. Its function is that, through the arrangement of the heat transfer plate 14, when the entire clean room needs to be heated, heat can be transferred to all the heat conducting sheets 6, so that the heated area in the box body 1 is increased.

[0025] Specifically, Figure 5 As shown, the heating rod 7 includes a first connecting member 15 and a second connecting member 16 respectively located on opposite sides of the mounting plate 12. Figure 6As shown, the thickness of the first connecting member 15 and the second connecting member 16 are both greater than the thickness of the moving groove 13, the thickness of the protrusion 17 is equal to the thickness of the moving groove 13, the length of the protrusion 17 is greater than the length of the moving groove 13, and the second connecting member 16 is provided with an embedding groove 18 on the end surface facing the first connecting member 15 for the protrusion 17 to be embedded through the section of the moving groove 13, and the cross section of the embedding groove 18 is the same in shape and size as the cross section of the protrusion 17. The roller 8 is arranged on the second connecting member 16, and the electric heating device is arranged on the first connecting member 15.

[0026] Specifically, Figure 4 As shown, the mounting frame 11 includes a vent plate 19 for air flow to pass through, the surface of the vent plate 19 is evenly hollowed out, and a plurality of evenly distributed regulating bodies 20 are arranged on the vent plate 19. A wind plate 21 arranged parallel to the vent plate 19 is also arranged in the box body 1, and a wind port 22 for the regulating body 20 to pass through is arranged on the wind plate 21, and the cross-sectional area of ​​the regulating figure gradually decreases toward the wind plate 21. The mounting frame 11 is provided with a distance adjustment device for adjusting the distance between the vent plate 19 and the wind plate 21. Its function is to adjust the length of the section where the regulating body 20 passes through the wind port 22 through the wind port 22, and to adjust the air volume through the wind port 22 by combining the design of the shape of the regulating body 20.

[0027] The maximum cross-sectional area of ​​the regulating body 20 is smaller than the cross-sectional area of ​​the air outlet 22. The function of this is that the regulating body 20 can be prevented from completely blocking the air outlet 22 by designing the maximum cross-sectional area of ​​the regulating body 20.

[0028] The vent plate 19 is arranged between the air passing plate 21 and the heat conducting sheet 6, and the heat conducting sheet 6 is arranged between the vent plate 19 and the heating rod 7. When the roller 8 is in contact with the heat conducting sheet 6, the heat conducting sheet 6 in contact with the roller 8 is in contact with the vent plate 19. The function is that, through the contact between the heat conducting sheet 6 and the vent plate 19, the heat transferred by the roller 8 received by the heat conducting sheet 6 can be transferred to the regulating body 20 on the vent plate 19 through direct contact. When the airflow passes through the gap between the regulating body 20 and the air passing port 22, the airflow can be made to directly contact the regulating body 20 as much as possible to be heated, thereby improving the heating efficiency.

The driving connection of the screw 24 located outside the box body 1 is connected with a knob, and the screw 24 is rotated by manually rotating the knob. A heat insulation section is provided between the screw 24 and the knob. Its function is that, through the arrangement of the threaded hole 23 and the screw 24, the vent plate 19 can be driven to make a linear motion along the axial direction of the screw 24 by rotating the screw 24.

[0030] Specifically, Figure 4 As shown, the flow equalizing plate 5 is in a groove shape, and flow equalizing holes 25 are evenly distributed on the bottom surface of the flow equalizing plate 5. The heating rod 7 is located between the air inlet 2 and the bottom surface of the flow equalizing plate 5. The side wall of the flow equalizing plate 5 and the side wall of the ventilation plate are filled with a heat insulation plate 26. Wind shields 27 are respectively connected to the opposite sides of the air passing plate 21. The wind shields 27 and the side walls of the flow equalizing plate 5 are connected end to end to form a closed whole that surrounds the outside of the air inlet 2 and is connected to the inner side of the surface of the box 1 where the air inlet 2 is located. Its function is that, through the setting of the wind shield plate 27, it can form a closed space outside the air inlet 2 together with the side wall of the flow equalizing plate 5, so that the airflow entering the box body 1 from the air inlet 2 can only flow out from the air outlet 22; through the setting of the heat insulation plate 26, it can prevent heat from being transferred to the flow equalizing plate 5 through direct contact, affecting the effect of local heating; through the design of the position between the flow equalizing plate 5 and the heating rod 7, the gas is adjusted in quantity and temperature before passing through the flow equalizing plate 5, so that the gas that has been adjusted in quantity and temperature can be evenly output to the outside of the high-efficiency air supply port.

[0031] The working principle of this embodiment is described as follows: when the clean room needs to be locally heated, the linear drive member extending out of the box body 1 is moved by hand to drive the heating rod 7 to move, so that the roller 8 contacts the heat-conducting sheet 6 that needs to be locally heated, and at the same time, the heat-conducting sheet 6 contacts the ventilation plate. The regulating body 20 on the ventilation plate adjacent to the area in contact with the heat-conducting sheet 6 is heated higher, so that the airflow passing through the local regulating body 20 is heated higher, thereby achieving the effect of adjusting the local temperature.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
