Description
Technical field
The present invention relates to a kind of human body infrared inductive switch, especially a kind of button human body infrared inductive switch.
Background technology
Human body infrared inductive switch is a kind of when someone passes through from infrared induction search coverage or close and automatic start
Switch, its main devices are human body pyroelectricity infrared sensor.Human body has constant body temperature, typically in 36--37 degree, meeting
The infrared ray of specific wavelength is sent, infrared sensor is used to detect the infrared ray that human body is sent, as passive type infrared probe is used for
Detect the infrared ray of 10 μm or so of human-body emitting wavelength, the Fresnel lenses that the infrared ray of human-body emitting passes through infrared sensing switch
Enhancing is gathered on infrared inductor, and infrared inductor generally use pyroelectricity element, this element is receiving human body infrared
Radiation temperature will lose charge balance when changing, and outwards discharge electric charge, and subsequent conditioning circuit can just trigger after handling after testing
Switch motion.Human body will be continuously turned on without departing from induction range, switch；Nothing is dynamic for a long time after people leaves or in induction region
Make, switch and automatic time delay is closed into load.
Current human body infrared inductive switch can only sense infrared ray and come trigger switch, and the installation position of infrared sensing switch
The normal work of switch can be influenceed with mode by putting, it occur frequently that triggering mistake, makes troubles to normal use, and influence switch
Service life.
The content of the invention
In order to solve the problems, such as that prior art is present, the present invention proposes a kind of button human body infrared inductive switch, existing
On the basis of somebody's body infrared sensing switch, by the redesign to Fresnel lens structure and controlling switch structure, make one
Body infrared sensing switch supports button to trigger control function manually in the case of surface structure is substantially unconverted, and this is simple in construction
Reliably, the Consumer's Experience of conventional body's infrared sensing switch is improved.
To realize above technical purpose, the technical scheme is that：Button human body infrared inductive switch, including luxuriant and rich with fragrance alunite
That lens and PCB, the Fresnel Lenses are covered on above PCB, and the PCB is provided with infrared induction
Device and photo resistance, it is characterised in that the Fresnel Lenses edge is provided with the support column being uniformly and symmetrically distributed, the support column
Spring is cased with outside, the PCB upper support column correspondence position is provided with jack, and the support column is interspersed in jack, described
Fresnel Lenses edge is additionally provided with the keyboard contact point being uniformly and symmetrically distributed, and keyboard contact point corresponds to position in the PCB
Button is installed, the keyboard contact point can be connected with button contact.
Further, the support column and keyboard contact point are two, and keyboard contact point is arranged between support column.
Further, the length of the support column is more than the length of keyboard contact point.
Beneficial effects of the present invention are：
1）The function of the function of Fresnel Lenses and separate physical key switch is combined into one, made outside human body infrared sensing switch
See it is constant in the case of, can be more flexible by button trigger switch, user's use by infrared induction trigger switch, and can
It is convenient；
2）Triggering and manual key Trigger Function are separate automatically for infrared induction, in pyroelectric sensing component failure, still
Control can be operated with manual switches, avoids the occurrence of the situation that the pyroelectric sensing component failure switch can not just use completely.
Brief description of the drawings
Fig. 1 is the decomposition texture schematic diagram of the present invention.
Brief description of the drawings：101- buttons, 102- jacks, 103-PCB wiring boards, 104- infrared inductors, 105- photo resistance,
201- Fresnel Lenses, 202- support columns, 203- springs, 204- keyboard contact points.
Embodiment
With reference to specific drawings and examples, the invention will be further described.
According to Fig. 1, button human body infrared inductive switch, including Fresnel Lenses 201 and PCB 103, institute
State Fresnel Lenses 201 and cover on the top of PCB 103, in addition to infrared inductor 104 and photo resistance 105, it is described infrared
Inductor 104 and photo resistance 105 are each provided in PCB 103, and the infrared ray sent for detecting human body, its feature exists
In the edge of Fresnel Lenses 201 is provided with the support column 202 being uniformly and symmetrically distributed, and spring is cased with outside the support column 202
203, the correspondence position of 103 upper support column of PCB 202 is provided with jack 102, and the support column 202 is interspersed in jack 102
Interior, the edge of Fresnel Lenses 201 is additionally provided with the keyboard contact point 204 being uniformly and symmetrically distributed, in the PCB 103
The correspondence position of keyboard contact point 204 is provided with button 101, and the keyboard contact point 204 can be connected with the contact of button 101.It is described
Support column 202 and keyboard contact point 204 are two, and keyboard contact point 204 is arranged between support column 202, the support
The length of post 202 is more than the length of keyboard contact point 204, and when ensureing that switch does not work, keyboard contact point 204 is with button 101
Separate discontiguous.
