The present invention provides a kind of far red light health pillow, for make the purpose of the present invention, technical solution and effect it is clearer,
Clear, the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that specific reality described herein
Example is applied only to explain the present invention, is not intended to limit the present invention.
Please refer to Fig. 1 and Fig. 2, the structural schematic diagram and detonation configuration of far red light health pillow respectively provided by the invention
Schematic diagram, the far red light health pillow 10 include pillow 20 and pillowcase 30, and the upper surface of the pillow 20 is provided with several
LED soft light rope 21, can be parallel or arranged in a crossed manner, can also be arranged according to preset style, the inside of pillow 20 is set
It is equipped with drive circuit board 22, the side of pillow 20 is provided with power interface 23, and the drive circuit board 22 is separately connected LED flexibility
Light bar 21 and power interface 23,30 housing of pillowcase are provided on pillow 20, and on pillowcase 30 for exposing LED flexible light
The first hollow out mouth 31 with 21 and the second hollow out mouth 32 for exposing power interface 23, the LED soft light rope 21 are remote red
Outer smooth LED soft light rope 21.
Wherein, the far red light that far red light LED soft light rope 21 issues is also known as LONG WAVE INFRARED light, wave-length coverage from
5.6 microns to 1000 microns.When far red light irradiation be heated material when, can make material absorb far red light after interior molecules and
Atom " resonance " generates thermal energy, to achieve the purpose that heating.Through research it is found that 8 ~ 14 micron wave lengths far infrared and human body
The wave band of radiation is identical, therefore the far infrared of the wave band has good heating physiotheraping effect to human body.
When being slept using the far red light health pillow, far red light can be issued by LED soft light rope 21, made
Obtaining pillow has heating effect.Also, this heating is a kind of warm for distributing generation from inside to outside, and the blood capillary at family can be used
Enlargement of pipe promotes blood circulation, and adjusts the state of mind so that the fatigue state of user be effectively relieved and improves the sleep matter of user
Amount.
In a further embodiment, transparent protecting film 33 is provided at the first hollow out mouth 31.30 housing of pillowcase exists
When on pillow 20, transparent protecting film 33 will be bonded LED soft light rope 21, not only can be to avoid direct body contact's LED flexible light
Band 21, moreover it is possible to play protective action.Frosting can be set by the surface of transparent protecting film 33 simultaneously, i.e., to transparent protecting film 33
Surface carry out frosted processing.In this way, the far red light that LED soft light rope 21 can be made to issue generates after transparent protecting film 33

Portion is different with the size on head, and being applicable in for LED health pillow can be improved in the first support portion 24 and the second support portion 25 of difference design
Property.For example, larger-size first support portion 24 can be used in the longer user of neck；Size may be used in the shorter user of neck
Lesser second support portion 25 brings more comfortable support effect so that health pillow can be bonded by making the neck of these two types of users.
Please continue to refer to Fig. 1 and Fig. 2, three flexible light bands are provided on pillow 20 provided in this embodiment, and it is parallel
It is arranged in the surface of pillow 20.In more embodiments, quantity, shape and the orientation of flexible light band can be adjusted.
The pattern that wavy, polyline shaped or combine more light bar to form specific shape such as is set by light bar, to promote far infrared
The aesthetics of light health pillow.
Vibromassage structure can also be arranged in position between the flexible light band, for convenient when user needs
Carry out massaging and physiotherapeutical.In addition, controlling for the convenience of the users the rule of sleep, light bar function can also be carried out according to sleep rule
The mode adjustment of rate, certainly it is preferred that multiple sensors can be set, such as vibrating sensor and audio sensor, the former
Can according to sleeper stir frequency adjustment corresponding power, such as in the case that stir than more frequently, power can be weakened,
Or in the case where finding the heavier situation of sleeper's sound of snoring, optical power is promoted.It but is on the whole, human health, on optical power has
Limit limitation.
Further, since far red light health pillow is in for a long time the directly state of contact human body in use, and use
Family may lead to vigilant decline into sleep in use, therefore have higher want to the safety of far red light health pillow
It asks.In the present embodiment, in order to separate the alternating current input circuit of high pressure with the ontology of health pillow, the far red light health care
