Description

Technical Field

[0001] The utility model belongs to the technical field of constant temperature heating, in particular to a constant temperature heating device. Background Art

[0002] In chemical research, researchers often need to prepare crystals. This process usually needs to be carried out at a specific temperature to control the growth rate and quality of the crystals. A constant temperature heating device is usually used to provide a stable temperature environment, which helps to obtain high-quality crystals.

[0003] The current constant temperature heating device is generally a box that can be sealed and heated internally, and can adjust the temperature through sensors and control circuits to achieve constant temperature. However, the air temperature distribution in the box is uneven and the circulation effect is poor, so the growth rate and crystal quality of the crystal are difficult to accurately control. For this reason, we propose a constant temperature heating device. Utility Model Content

[0005] The telescopic mechanism includes a driving motor, a gear, a limit plate and a ventilation assembly. The driving motor and the limit plate are fixedly installed on the inner wall of the box. The output end of the driving motor is fixedly sleeved with a gear, and the gear is meshed and connected to the ventilation assembly. The ventilation assembly is slidably connected between the inner wall of the box and the limit plate.

[0006] The ventilation assembly includes a rack, a ventilation pipe, a base and a fan, the rack is meshed with a gear, the rack is slidably connected between the inner wall of the box and the limit plate, one end of the rack is fixedly mounted with a base, a ventilation pipe is mounted on the base, a fan is mounted at one end of the ventilation pipe, the fan faces the baffle, the fan extends out of the box to lift the baffle, and the rotation of the fan helps to draw air outside the box into the box.

[0007] Limiting protrusions are relatively arranged on two opposite side walls of the constant temperature chamber, and the two relatively arranged limiting protrusions have the same height. A tray is slidably connected to the limiting protrusions. There can be multiple limiting protrusions. Setting the limiting protrusions helps to adjust the height of the tray and thus adjust the distance between the tray and the heating tube.

[0008] A filter cover is provided between the constant temperature chamber and the telescopic mechanism, and the area of ​​the filter cover is the same as the cross section of the inner cavity of the box body. The filter cover can prevent dust in the air from entering the constant temperature chamber and contaminating the crystal.

[0012] By opening the sliding door, placing the tray on the limit protrusion at an appropriate height, then closing the sliding door, setting the temperature through the control panel, starting the device to allow the heating tube to preheat the constant temperature chamber. When the constant temperature chamber reaches the preset temperature, open the sliding door and place the container containing the crystal on the tray, and then close the sliding door for constant temperature treatment. During the constant temperature process of the device, the driving motor will automatically rotate according to the temperature of the constant temperature chamber, and drive the rack to slide toward the outside of the box along the limit plate and the inner wall of the box through the rotation of the gear, so that the fan pushes the baffle outward. The fan rotates to suck the air outside the box into the box through the ventilation pipe, and then passes through the filter cover to filter the dust in the air and introduce the wind into the constant temperature chamber, so that the air in the constant temperature chamber flows, achieving a balanced distribution of temperature in the constant temperature chamber. After the air circulates for a certain period of time, the driving motor rotates in the opposite direction, and the fan is retracted into the box through the rack. The baffle falls naturally to prevent heat from spreading as the baffle is opened. BRIEF DESCRIPTION OF THE DRAWINGS
