Embodiment 1

[0054] Such as figure 1 As shown, a biological safety cabinet equipped with a door body that can be easily opened and closed includes: a casing 1 of the safety cabinet and a cabinet door 2 arranged on the casing 1 that can be raised and lowered. The cabinet door 2 is provided with an induction magnet 21, and the housing 1 is provided with a magnetic control sensor that detects the position of the cabinet door 2 by identifying the induction magnet 21, and the magnetic control sensor communicates with the control unit The power source that the cabinet door rises and falls is connected.

[0055] In this embodiment, the induction magnet 21 is arranged at one end of the bottom of the cabinet door 2 , and the induction magnet 21 can also be arranged at both ends of the cabinet door 2 at the same height. The housing 1 is provided with a first magnetron sensor 11 for detecting whether the cabinet door 2 is in the closed position, and a second magnetron sensor 13 for detecting whether...

Embodiment 2

[0066] Such as figure 2 As shown, a biological safety cabinet equipped with a door body that can be easily opened and closed includes: a casing 1 of the safety cabinet and a cabinet door 2 arranged on the casing 1 that can be raised and lowered. The cabinet door 2 is provided with an induction magnet 21, and the housing 1 is provided with a magnetron sensor that cooperates with the induction magnet 21 to detect the position of the cabinet door 2, and the magnetron sensor is controlled by The unit is connected with the power source for the up and down of the cabinet door.

[0067] In this embodiment, the induction magnet 21 is arranged at one end of the bottom of the cabinet door 2 . The housing 1 is provided with a first magnetron sensor 11 for detecting whether the cabinet door 2 is in the closed position, and a second magnetron sensor 13 for detecting whether the cabinet door 2 is in the highest position. The housing 1 of the safety cabinet is provided with a positioning ...

Abstract

The invention discloses a biosafety cabinet with a door capable of conveniently opening and closing and a control method of a cabinet door. The biosafety cabinet comprises a shell of the safety cabinet and a cabinet door, wherein the cabinet door is arranged on the shell and can lift and descend, and an induced magnet is arranged on the cabinet door; a magnetic control inductor which is matched with the induced magnet and used for detecting the position of the cabinet door is arranged on the shell, and the magnetic control inductor is connected with a power supply for the cabinet door to lift and descend through a control unit; the cabinet door of the safety cabinet is driven to lift and descend by the power supply; when the cabinet door of the safety cabinet is moved to a working position, the induced magnet on the cabinet door is detected by the magnetic control inductor arranged on the shell of the safety cabinet, a signal is sent by the magnetic control inductor to the control unit, and a signal for determining the working position of the cabinet door of the safety cabinet is generated by the control unit. By using the device and the mode, the cabinet door can be quickly and accurately positioned in the working position, and secondary regulation of the position of the cabinet door is avoided.

Description

technical field [0001] The invention relates to a cabinet door of a biological safety cabinet in the field of automatic control of the safety cabinet, in particular to a biological safety cabinet equipped with a door body which can be easily opened and closed and a control method for the cabinet door. Background technique [0002] Biological safety cabinets are used to protect the operator, the laboratory environment and experimental materials from exposure to the above-mentioned operations when operating infectious experimental materials such as primary cultures, bacterial strains, and diagnostic specimens. Designed for the possible generation of infectious aerosols and splashes. [0003] Biological safety cabinets are widely used in medical and health care, disease prevention and control, food hygiene, biopharmaceuticals, environmental monitoring, and various biological laboratories. They are an important basis for ensuring biological safety and environmental safety, and b...
