Description
Technical field
The present invention relates to passive type infrared acquisition, and in particular to the infrared spy of primary polyethylene in IRDS
Head shell.
Background technology
With the development of society, the various automatic control systems for being convenient to life have initially entered the life of people, with heat
It is exactly one of them to release the automatic door unit that electric infrared sensor is core.Pyroelectric infrared sensor is former based on pyroelectric effect
The electrothermic type infrared sensor of reason.Its internal thermoelectricity member by high Seebeck coefficient ferrotitanium lead plumbate mercury ceramics and lithium tantalate, sulphur
Light microscopic piece window composition is considered in the cooperations such as sour three sweet iron, and it polarizes variation with temperature and changed.Pyroelectric infrared sensor is by passing
Sense detection member, interferometric filter and FET adaptation three parts composition.Certain thickness should be made in high thermoelectric material during design
The thin slice of degree, and metal electrode is plated on its two sides, then power up and it is polarized, pyroelectricity detection has so just been made
Member.In order to improve the signal to noise ratio of sensor, typically Fresnel Lenses need to be added before sensor measuring member.Fresnel Lenses is using thoroughly
" blind area " and " highly sensitive area " of the special optical principle of mirror, before the detectors one alternating change of side's generation, to improve its
Detect receiving sensitivity.When someone walked before lens it is out-of-date, the infrared ray that human body is sent just constantly alternately from " blind area " enter
" highly sensitive area ", the infrared signal for thus making to receive are inputted with dynamic impulse form, so as to its strong energy amplitude.
Fresnel Lenses effect has two：First, focussing force, will heat release infrared signal refraction (reflection) on PIR, second is made
With being that will be divided into several area pellucidas and dark space in search coverage, enable the mobile object into search coverage with the shape of temperature change
Formula produces change heat on PIR and releases infrared signal.
But due to the volume very little of pyroelectric infrared transducer, typically in 1cm or so, therefore Fresnel Lenses is more difficult
To be fixed on the sensor measuring of infrared probe member top.Therefore, pyroelectric infrared transducer can be firmly mounted to by how manufacturing
On Fresnel Lenses, be a significant research topic.
The content of the invention
Present invention aims at the more difficult fixed installation of Fresnel Lenses solved on current pyroelectric infrared transducer.For
Above mentioned problem, the invention provides the primary polyethylene infrared probe shell in IRDS, its application can incite somebody to action
Fresnel Lenses is firm to be easily arranged on pyroelectric infrared transducer, and protection can be played to pyroelectric infrared transducer and is made
With.
The purpose of the present invention is achieved through the following technical solutions：
Primary polyethylene infrared probe shell in IRDS, including Fresnel Lenses, base and kelly,
The Fresnel Lenses is fixed on the upper surface of base, and the side of the base is provided with axle bed, and the kelly is L-type, the card
The stock end of bar is connected by rotating shaft with axle bed, and the quarter butt end of the kelly is provided with buckle.Lens are directly fixed
On shell, Fresnel Lenses can be also integrated with while pyroelectric infrared transducer is protected；After kelly is rotated, by L-type
The buckle of the quarter butt end of kelly is stuck on base, and locking action can be achieved.
Further, the side of base is provided with breach.Breach is reserved for the base pin of pyroelectric infrared transducer, can be with
The present invention is set more to be bonded the structure of pyroelectric infrared transducer when in use.
Further, Fresnel Lenses is fixed on the upper surface of base by thermoplastic processes.The whole of the present invention can be improved
Body and reliability.
Further, the material of Fresnel Lenses, base and kelly uses primary polyethylene compared with prior art.Using
Primary polyethylene can improve the global reliability of the present invention and will not discharge peculiar smell.
The invention has the advantages that：Including Fresnel Lenses, base and kelly, Fresnel Lenses is fixed on base
Upper surface, the side of base is provided with axle bed, and kelly is L-type, and the stock end of kelly is connected by rotating shaft with axle bed, kelly
Quarter butt end be provided with buckle.In the use of the present invention, its application can both protect pyroelectric infrared transducer or be integrated with phenanthrene
Nie Er lens, it can be consolidated by L-type kelly and be easily arranged on pyroelectric infrared transducer.
