Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to an ultraviolet sterilization device for an experimental cabin. Background Art

[0002] Ultraviolet rays can break up the DNA or RNA gene chains of bacteria, making them unreplicable, thereby achieving the purpose of sterilization. Ultraviolet sterilization is a physical destruction process, which is not affected by chemical equilibrium conditions such as temperature, concentration, and activity, and has the advantages of being non-toxic, mercury-free, residue-free, odor-free, and having a high spectrum. Ultraviolet rays are especially needed for sterilization in experimental chambers that require sterilization.

[0003] The existing sterilization devices in the experimental cabin generally use mercury lamps, which are fixed and hoisted on the top of the experimental cabin and emit ultraviolet rays to sterilize the experimental cabin. The principle of mercury lamps emitting ultraviolet rays is to heat the mercury metal inside, evaporate it into mercury vapor, and then discharge it through the energized electrode to generate ultraviolet rays; however, when the mercury lamp emits ultraviolet rays, it will generate a lot of heat, causing the internal heating of the mercury lamp to be more serious. When the mercury lamp is turned on for the second time, it is necessary to wait for the mercury lamp to cool down before continuing to emit ultraviolet rays. However, since the mercury lamp itself has no heat dissipation device, the cooling time is long, which is easy to affect the progress of the experiment; and because the sterilization times in the experimental cabin are frequent, the mercury lamp is also frequently turned on and off, which is not conducive to the cooling of the mercury lamp and is easy to shorten the service life of the mercury lamp.

[0032] In a specific implementation, when the number of fans 41 is one, the air inlet of the fan 41 faces the outside of the shell 1, and the air outlet faces the inside of the shell 1; when the number of fans 41 is two, the air inlet of one of the fans 41 faces the outside of the shell 1, the air outlet of one of the fans 41 faces the inside of the shell 1, the air inlet of the other fan 41 faces the inside of the shell 1, and the air outlet of the other fan 41 faces the outside of the shell 1, thereby achieving a better gas flow effect in the shell 1 and a better heat dissipation effect.

For example, if the housing 1 in the present invention is a rectangular parallelepiped with four side walls and two end faces, then the number of the sterilization components 3 in the present invention is four.

[0034] The shell 1 of the utility model is provided with an exhaust and heat dissipation channel, which enhances the ventilation of the shell 1; multiple groups of sterilization components 3 are fixed on the shell 1, so that the utility model can perform multi-faceted sterilization on the inside of the experimental cabin; when the sterilization components 3 are started to sterilize the inside of the experimental cabin, the heat generated is concentrated inside the shell 1 and on multiple side walls of the shell 1, and the fan 41 is started, and the fan 41 blows air to the inside of the shell 1, so that the heat inside the shell 1 is discharged through the fan 41, and then the heat on the multiple side walls of the shell 1 is conducted to the multiple heat dissipation fins 42 by heat conduction, which not only enhances the heat dissipation effect of the sterilization component 3 and extends the service life of the sterilization component 3, but also shortens the cooling time of the sterilization component 3, reducing the impact on the progress of the experiment.

[0037] Optionally, the adjustment assembly 5 includes three drive motors, a hydraulic cylinder 51, a first fixed seat 52, a second fixed seat 53, a rotating plate 54 and a third fixed seat 55, the first fixed seat 52 is fixed on an external plane, the rotating plate 54 is sleeved inside the first fixed seat 52, the outer wall of the rotating plate 54 is rotatably connected to the inner wall of the first fixed seat 52, one end of the second fixed seat 53 is fixedly connected to a side surface of the rotating plate 54, the other end of the second fixed seat 53 is rotatably connected to the cylinder body of the hydraulic cylinder 51, the third fixed seat 55 is fixed on one of the end covers 2, the third fixed seat 55 is rotatably connected to the telescopic rod of the hydraulic cylinder 51, the output shaft of the first drive motor is connected to the rotating plate 54, the output shaft of the second drive motor is connected to the cylinder body of the hydraulic cylinder 51, and the output shaft of the third drive motor is connected to the third fixed seat 55.

[0038] Specifically, in the present invention, the inner wall of the first fixed seat 52 and the outer wall of the rotating plate 54 are connected via a rolling bearing, thereby realizing the rotational connection between the first fixed seat 52 and the rotating plate 54 .

[0039] Furthermore, in the present invention, the first fixing seat 52 is installed on the top of the experimental cabin by means of a plurality of screws. If the present invention is applied in different spaces, the present invention can be fixed on any plane in the space by means of screws.

[0040] In a specific implementation, by starting the first drive motor, the output shaft of the first drive motor drives the rotating plate 54 to rotate, and under the action of the rolling bearing, the rotating plate 54 rotates 360° in the first fixed seat 52, thereby realizing the adjustment of the irradiation angle of the sterilization component 3 and the shell 1 in the experimental cabin; by starting the second drive motor, the output shaft of the second drive motor drives the cylinder body of the hydraulic cylinder 51 to rotate in the second fixed seat 53, thereby realizing the adjustment of the angle between the hydraulic cylinder 51 and the second fixed seat 53; by starting the third drive motor, the output shaft of the third drive motor drives the third fixed seat 55 to rotate, thereby realizing the adjustment of the angle between the shell 1 and the hydraulic cylinder 51; by starting the hydraulic cylinder 51, the telescopic rod of the hydraulic cylinder 51 performs a telescopic movement, thereby realizing the adjustment of the irradiation height of the sterilization component 3 and the shell 1 in the experimental cabin.

[0043] Specifically, when the housing 1 of the present invention is a rectangular parallelepiped, the number of the circuit boards 31 is four.

[0044] The utility model adopts ultraviolet LED 32 to sterilize the inside of the experimental cabin. Compared with the mercury lamp, the current required to start the ultraviolet LED 32 is smaller than the current required to start the mercury lamp, so the ultraviolet LED 32 starts faster; and the ultraviolet LED 32 is more environmentally friendly; in actual application, after a long period of irradiation, the heat generated by the ultraviolet LED 32 is less than the heat generated by the mercury lamp, the cooling speed is faster, the service life is longer, and the cost of equipment replacement and maintenance is reduced.

[0045] Optionally, an ultraviolet sterilization device for an experimental chamber further includes a plurality of light-transmitting plates 6 , wherein the plurality of light-transmitting plates 6 are respectively fixed on the outside of the plurality of side walls of the shell 1 , and the plurality of light-transmitting plates 6 are respectively located on the outside of the plurality of circuit boards 31 .

[0046] Specifically, when the housing 1 of the present invention is a rectangular parallelepiped, the number of the light-transmitting plates 6 is four.

[0047] The plurality of light-transmitting plates 6 are arranged on the outside of the circuit board 31 , which can reduce the dust and bacteria adhering to the surfaces of the circuit board 31 and the plurality of ultraviolet LEDs 32 , and reduce the frequency of cleaning the sterilization component 3 .

[0049] By providing two slide grooves 7 at intervals on the outer surface of each side wall of the housing 1 , the light-transmitting plate 6 and the circuit board 31 can be detachably connected to the housing 1 , so that the light-transmitting plate 6 and the circuit board 31 can be easily replaced.

[0050] Optionally, a power cord hole 8 is opened on one of the end covers 2, and the power cord of the fan 41 and the power cords of the plurality of circuit boards 31 are connected to an external power source after passing through the power cord hole 8.

[0051] Optionally, an ultraviolet sterilization device for an experimental chamber further includes a controller, and the three drive motors and the hydraulic cylinder 51 in the adjustment component 5 are electrically connected to the controller.

[0052] In a specific implementation, when the sterilization component 3 is working, the staff should avoid approaching the irradiation range of the sterilization component 3 to prevent injury. Therefore, the controller can control the timed start of the three drive motors and the hydraulic cylinder 51, so that the sterilization component 3 can adjust the irradiation angle and irradiation height in the experimental cabin at regular intervals.

[0053] Furthermore, the multiple circuit boards 31 and fans 41 in the utility model are all connected to an external power supply. On this basis, the external power supply in the utility model can be a driving power supply. The controller is electrically connected to the driving power supply.

The controller controls the driving power supply according to the signal to realize the control of the operation or stop of the circuit board 31 and the fan 41.

[0055] The specific process of the controller controlling the operation or stop of the circuit board 31 and the fan 41 is as follows: a microwave radar sensing sensor is fixed on the top of the experimental cabin. When the microwave radar sensing sensor detects the movement of a staff member or an object within the detection range, a signal is transmitted to the controller, and the controller controls the driving power supply to disconnect the power supply to the circuit board 31 and the fan 41, thereby stopping the operation of the sterilization component 3 and the heat dissipation component 4; when the microwave radar sensing sensor does not detect the movement of a staff member or an object within the detection range, a signal is transmitted to the controller, and the controller controls the driving power supply to power the circuit board 31 and the fan 41, thereby starting the sterilization component 3 and the heat dissipation component 4.

[0056] By setting up a controller and a microwave radar sensing sensor, it is possible to realize the automatic start and stop of the sterilization component 3 and the heat dissipation component 4 to avoid injuries to the staff under the irradiation of the ultraviolet LED 32, and it is also possible to realize the timed adjustment of the position of the sterilization component 3 in the experimental cabin, so as to realize the automatic multi-angle and multi-directional sterilization work of the sterilization component 3 in the experimental cabin.

[0057] Optionally, the material of the plurality of light-transmitting plates 6 is quartz glass.

[0059] Optionally, the shell 1 is made of one of aluminum, magnesium, aluminum alloy, and aluminum-magnesium alloy.

[0060] Considering the manufacturing cost, the housing 1 of the present invention is made of any one of the above materials, and the manufactured housing 1 is light in weight, which can reduce the load of the adjustment component 5 .

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
