Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, in particular to a high-temperature hot air circulation type disinfection cabinet. Background Technique

[0002] The existing disinfection cabinets refer to disinfecting and sterilizing the items stored in the disinfection cabinet body through ultraviolet rays, far-infrared rays, high temperature, ozone, etc. When using far-infrared rays to disinfect the disinfection cabinet, since the installation position of the heat source in the disinfection cabinet body is relatively fixed, when the heat source heats up, the local temperature in the disinfection cabinet body will be too high. If it is necessary to ensure that the temperature requirements are met everywhere in the cabinet body, it is necessary to increase the power consumption of the heat source. Although the disinfection effect is ensured, it undoubtedly increases the energy consumption and is not conducive to energy conservation and environmental protection. Moreover, when there are many items inside the cabinet, the air does not circulate, and the temperature is more difficult to be evenly distributed. Content of the Utility Model

[0003] To solve the above problems, that is, to solve the problems proposed in the above background technique, the utility model provides a high-temperature hot air circulation type disinfection cabinet, which includes a cabinet body, a box body and a pair of circulation pipes.

[0019] The following will Figures 1-4 describe the preferred implementation manners of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0020] The present utility model proposes a high-temperature hot air circulation disinfection cabinet. When using this device, the two power connection ends of the serpentine electric heating wire 11 are electrically connected to an external power supply. The electric push rod 1 is started, and the output end of the electric push rod 1 retracts, driving the push plate 13 and the sealing cover 8 to slide along the through groove towards the direction close to the electric push rod 1. When the output end of the electric push rod 1 is completely retracted, the other end of the sealing cover 8 is located in the through groove, and at this time, the cabinet body 12 is in an open state. Check the situation of the filter plate 9. If the filter plate 9 is saturated, replace it with a new filter plate 9 and place it on a pair of clamping plates. Place the items to be disinfected on the corresponding tray 5. Slide a pair of trapezoidal slide bars 15 corresponding to one tray 5 into the corresponding trapezoidal slide grooves 14, and place the tray 5 in a suitable pair of trapezoidal slide grooves 14 according to the height of the items. After placing the tray 5, close the movable door. Start the electric push rod 1 again. The output end of the electric push rod 1 extends to drive the sealing cover 8 to slide in the reverse direction. After the sealing cover 8 is in a semi-open state, start the motor 7 and the external power supply, and open the solenoid valve of the circulation pipe 3 at the end close to the electric push rod 1. The serpentine electric heating wire 11 generates heat, and the motor 7 drives the air extraction fan 10 to rotate. The air extraction fan 10 sucks air into the cabinet body 4. The air passes through the filter plate 9, and the filter screen of the filter plate 9 cooperates with the activated carbon to adsorb impurities in the air. The air extraction fan 10 blows the air over the serpentine electric heating wire 11 to generate high-temperature hot air. The high-temperature hot air enters the cabinet body 4, and the hot air blows through the items and the through holes of the tray 5 and blows to the bottom of the cabinet body 4. The cold air at the bottom of the cabinet body 4 circulates to the inside of the cabinet body 12 through a circulation pipe 3. Observe the change of the temperature inside the cabinet body 4 through the thermometer 6. If the temperature rises slowly, reduce the opening between the sealing cover 8 and the cabinet body 12 to make the temperature inside the cabinet body 4 rise rapidly. When the temperature inside the cabinet body 4 gradually stabilizes and the value of the thermometer 6 no longer changes, close the sealing cover 8, and the other end of the sealing cover 8 is clamped into the card slot. At this time, the inside of the cabinet body 4 is in a sealed state. Open the solenoid valve of the other circulation pipe 3. The air extraction fan 10 and the pair of circulation pipes 3 cooperate to make the inside of the cabinet body 4 perform high-temperature hot air circulation, achieving the purpose of high-temperature hot air disinfection, replacing the problem of uneven heat source distribution of traditional disinfection cabinets. Turn off the external power supply. Since the cabinet body 4 is a heat-insulating cabinet body, even if the serpentine electric heating wire 11 no longer continuously generates heat, the heat reduction inside the cabinet body 4 is relatively slow, reducing energy consumption. If the temperature inside the cabinet body 4 is close to the set minimum temperature, start the external power supply again to keep the hot air inside the cabinet body 4 at a high temperature state all the time. Observe the pressure inside the cabinet body 4 through the pressure gauge 2 (hot air circulation will cause the temperature inside the cabinet body 4 to rise. According to the principle of thermal expansion and contraction of gases, the volume of the gas will expand when the temperature rises, so the pressure inside the cabinet will increase. Therefore, the sealing cover 8 can only be closed after the temperature inside the cabinet body 4 tends to be stable. Similarly, the temperature inside the cabinet body 4 will decrease after a long time of hot air circulation, which will still affect the pressure inside the cabinet body 4. Therefore, not only the thermometer 6 is needed to measure the temperature inside the cabinet body 4, but also the pressure gauge 2 is needed to observe the pressure inside the cabinet body 4). If the pressure inside the cabinet body 4 changes greatly,Then slightly open the sealing cover 8 (to avoid heat loss), adjust the pressure inside the cabinet body 4 to a stable state, and then close the sealing cover 8 again. During the hot air circulation, the moisture-proof boxes at the air inlet ends of a pair of circulation pipes 3 adsorb the water vapor inside the cabinet body 4, so that the inside of the cabinet body 4 always remains dry during the high-temperature hot air disinfection. After the disinfection is completed, turn off the motor 7, and replace the moisture-proof boxes and the filter plate 9 regularly.
