Description
Technical field
The present invention relates to the cabinet door of a kind of Biohazard Safety Equipment of safety cabinet automation field, particularly a kind of be equipped with can easy switch gate body Biohazard Safety Equipment and cabinet door control method.
Background technology
Biohazard Safety Equipment is while having infective experiment material for operation primary culture, bacterium strain and diagnostic sample etc.; be used for protecting operator, laboratory environment and experiment material, make it avoid being exposed to issuable infectious aerosol and spatters in aforesaid operations process and design.
Biohazard Safety Equipment is widely used in health care, disease prevention and control, food hygiene, bio-pharmaceuticals, and the fields such as Environmental Monitoring and different kind organism laboratory are the important foundations that ensures bio-safety and Environmental security, belong to the category of " people's livelihood " metering.Before 30 years, Biohazard Safety Equipment detects to be carried out abroad, the standard of Main Basis European Union or the U.S. at present.At home, at present also ununified Biohazard Safety Equipment detects national standard, and Biohazard Safety Equipment detection method is very chaotic, the standard of the existing Ministry of Construction has again the standard of Bureau of Drugs Supervision, adopts in addition the company standard of European Union's standard, Unite States Standard or each factory.
At present, Biohazard Safety Equipment glass door motor drags generally application, but can only control the continuous lifting of glass door by control panel by key control.The operating position of Biohazard Safety Equipment glass door is the concrete height value of determining, as highly there being deviation will cause warning, but the easy contraposition of manual adjustments height is inaccurate, and causing reports to the police constantly occurs.Thereby, not only increased user's operating frequency, and caused the waste in user time.
In order to address the above problem, existing patented technology has proposed solution to the problems referred to above:
As the Chinese patent locating hinge that application number is CN92237552.6, it is by brake block stage clip riveting pin is restricted mutually, and frequently, stage clip embeds the cupboard door that the spring hole locating hinge bottom brake block is installed for friction, running.Thereby, realize the location that cupboard door utilizes hinge to realize, but utilized said apparatus, easily cause location inaccuracy, cannot realize the action effect of smoothly locating by location simultaneously.
Application number is a kind of cabinet door of Chinese patent positioner of CN201020291742.1, this positioner comprises the positioning sleeve being arranged on cabinet, in positioning sleeve, inlay back-moving spring, the positioning sleeve openend of the other end of back-moving spring is provided with steel ball, steel ball is embedded in the opening of positioning sleeve, and corresponding steel ball position cabinet door is provided with locating hole.In the time closing cabinet door, steel ball is compressed to be recovered in positioning sleeve like this, and in the time that the locating hole on cabinet door is aimed at steel ball, steel ball is embedded in locating hole and realizes and locating under the effect of back-moving spring.But said apparatus, by spring-operated, easily causes wearing and tearing, failure-frequency increases.And it cannot realize the object that seamlessly transits location place equally.
In view of this, special proposition the present invention.
Summary of the invention
The invention provides a kind of be equipped with can easy switch gate body Biohazard Safety Equipment and cabinet door control method, by magnetic switch and location magnetic sheet are set on safety cabinet, safety cabinet door can be located fast to its position, and can make cabinet door realize the object of opening and closing smoothly.Another object of the present invention is to provide a kind of control method of biological safety cabinet door, makes it the whether object in position location of cabinet door can in opening process, be detected rapidly, exactly.
For realizing goal of the invention, adopt following technical scheme: a kind of be equipped with can easy switch gate body Biohazard Safety Equipment, comprising: the housing of safety cabinet and be arranged on housing can rise and fall cabinet door.On described cabinet door, be provided with induced magnet, be provided with the magnetic control inductor that comes detecting box door position by identification induced magnet on described housing, described magnetic control inductor is connected with the power source of cabinet door rise and fall by control module.
Further, on described housing, be provided with the whether first magnetic control inductor at place in the close position of detecting box door, with detecting box door whether in opening the second magnetic control inductor at maximum position place.
Further, whether on the housing of safety cabinet, be provided with detecting box door in the location at operating position place magnetic control inductor.Described location magnetic control inductor is arranged between the first magnetic control inductor and the second magnetic control inductor.Described the first magnetic control inductor, the second magnetic control inductor and location magnetic control inductor are connected with control module respectively.
Further, described location magnetic control inductor comprises, whether detecting box door whether the second location magnetic control inductor in the second working depth position of the first location magnetic control inductor in the first working depth position, detecting box door ... whether detecting box door the location of the n in n working depth position magnetic control inductor.
Have the cabinet door control method that Biohazard Safety Equipment that can easy switch gate body is housed described in as above arbitrary, the cabinet door of safety cabinet can rise and fall under the drive of power source.The cabinet door of described safety cabinet is in the time moving to operating position place, the magnetic control inductor arranging on the housing of safety cabinet detects the induced magnet on cabinet door, magnetic control inductor sends signal to control module, the decision signal of the cabinet door of control module generation safety cabinet in operating position.
