Embodiment Construction

[0022] Combine below figure 1 The present invention is further elaborated.

[0023] The invention provides a biological safety cabinet capable of reminding the life of an ultraviolet lamp, wherein a life presetting device, a time processing device and an alarm device are arranged on the control panel of the biological safety cabinet;

[0024] The workflow of the UV lamp life reminder of the biological safety cabinet provided by the present invention is as follows: figure 1 As shown in the figure, the life presetting device is used to preset the service life of the UV lamp, and each time the user updates the UV lamp, he can input the length of the service life into the service life according to the expected service life of the UV lamp specified by the UV lamp. In the preset device; the time processing device is used to record the cumulative running time of the ultraviolet lamp, and retrieve the preset life of the ultraviolet lamp from the life preset device, and according to "...

Abstract

The invention relates to a biosafety cabinet capable of prompting life of an ultraviolet lamp. A control panel of the biosafety cabinet is provided with a life preset device, a time processing device and an alarming device. The life preset device is used for presetting a service life of the ultraviolet lamp; and the time processing device is used for recording cumulative operation time of the ultraviolet lamp and calculating the residual service life of the ultraviolet lamp according to a formula: the service life of the ultraviolet lamp=(the preset life-the cumulative operation time) / the preset life*100%. When the residual service life of the ultraviolet lamp is less than 10%, the alarming device sends out an alarming signal to prompt a user to replace the ultraviolet lamp. The provided biosafety cabinet capable of prompting the residual service life of the ultraviolet lamp is simple in device and low in cost, and can greatly save work load of the user to check the ultraviolet lamp.

Description

technical field [0001] The invention specifically relates to a biological safety cabinet which can remind the remaining service life of an ultraviolet lamp. Background technique [0002] The biological safety cabinet is used to protect the operator, laboratory environment and experimental materials from exposure to the above-mentioned operation process when handling infectious experimental materials such as primary cultures, bacterial strains and diagnostic specimens. Designed for possible infectious aerosols and splashes. Biosafety cabinets are widely used in medical and health, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring and various biological laboratories. They are an important basis for ensuring biosafety and environmental safety. [0003] In view of the dangerous use environment of biological safety cabinets, during installation and at regular intervals thereafter, professionals from the National Air-conditioning Equipment...
