Description

Technical Field

[0001] The invention relates to the field of biosafety and medical technology, and in particular to an ultraviolet disinfection device. Background Art

[0002] Biosafety and biomedical laboratories widely use laboratory equipment such as pipettes and transfer windows. Due to the possibility of contact with pathogenic microorganisms, pipettes are currently sterilized by high pressure, which is time-consuming, labor-intensive and extremely inconvenient. Most laboratories do not handle it in a timely manner, and there is a risk of cross-contamination of microorganisms, which has become a major pain point for biomedical testing laboratories. Most transfer windows are disinfected by ultraviolet light, which requires regular monitoring with ultraviolet indicator cards and timely replacement, which is labor-intensive.

[0003] Therefore, how to select a suitable, convenient and efficient disinfection device is a problem that technical personnel in this field need to solve urgently. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an ultraviolet disinfection device to solve the deficiencies in the prior art. The present invention not only ensures the disinfection effect, but also reduces the frequency of replacing ultraviolet lamps, reduces costs and increases efficiency, and realizes the disinfection of experimental equipment such as pipettes and transfer windows.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] An ultraviolet disinfection device comprises a box, an ultraviolet lamp, an ultraviolet intensity sensor, a control circuit and a touch screen;

[0007] The box body is a hollow cavity, which includes a component cavity and a disinfection cavity connected in sequence from bottom to top, and the side of the disinfection cavity is sealed by a sealed cover;

[0008] The UV lamp and UV intensity sensor are placed in the disinfection chamber;

[0009] The control circuit and the touch screen are both placed in the component cavity, and the control circuit is connected to the ultraviolet lamp, the ultraviolet intensity sensor and the touch screen through lines respectively to control their operation.

[0010] Furthermore, the chassis is a hollow cavity in which the various components are installed.

[0011] Furthermore, the above-mentioned ultraviolet lamp is a UVC deep ultraviolet waterproof sterilization and disinfection module, which is installed on the top, bottom or side of the disinfection chamber, and the number is 1-12.

[0012] A further beneficial effect of the above method is that the ultraviolet lamp can be used to disinfect experimental instruments such as pipettes and transfer windows placed in the disinfection chamber.

[0013] Furthermore, the ultraviolet intensity sensor is used to monitor the ultraviolet intensity in real time and turn on an appropriate number of ultraviolet lamps according to the ultraviolet intensity. When the ultraviolet intensity decreases and all the ultraviolet lamps are turned on but still fail to reach the irradiation dose, the ultraviolet lamps are promptly prompted to be replaced, and data is saved and printed through a USB interface and a micro printer.

[0014] Furthermore, the control circuit is used to automatically calculate the irradiation time according to the set ultraviolet irradiation dose.

[0015] Furthermore, the above-mentioned touch screen is a commonly used component, and its function is to display and set operating parameters and status.

[0016] Furthermore, the above-mentioned ultraviolet disinfection device also includes a bracket, which is placed in the disinfection chamber and is provided with 1-10 experimental equipment placement positions with hook and groove structures, which are inclined at 60°-90° and can rotate 360°.

[0017] A further beneficial effect of adopting the above method is that the bracket is a processed part used to place experimental instruments, and can place 1 to 10 experimental instruments including pipettes at the same time, and can rotate 360 ​​degrees to facilitate the placement of experimental instruments.

[0018] It can be seen from the above technical solution that compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Use ultraviolet intensity sensor to monitor ultraviolet intensity in real time, realize digitalization, do not need to use ultraviolet indicator card for regular monitoring, and reduce labor intensity;

[0020] 2. Use the control circuit to automatically calculate the irradiation time according to the set ultraviolet irradiation dose to ensure the disinfection effect;

[0021] 3. Turn on the appropriate number of UV lamps according to the intensity of ultraviolet rays, which reduces the frequency of replacing UV lamps and reduces costs and increases efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
