Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that "connected" and words used in this application to express "connected," such as "connected," "connected," and the like, include both direct connection of one element to another element and connection of one element to another element through another element.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when used in this specification the singular forms "a", "an" and/or "the" include "specify the presence of stated features, steps, operations, elements, or modules, components, and/or combinations thereof, unless the context clearly indicates otherwise.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

As shown in fig. 1-5, the present embodiment provides a bed curtain support with an infrared sensor, the bed curtain support includes a bed curtain support body 2 and a fan 5 disposed on the bed curtain support body, the bed curtain support body 2 is disposed on a bed, and is of a rectangular frame structure, and includes an upper square frame and four fixing rods connected to four corners of the upper square frame and longitudinally disposed, lower ends of the four fixing rods are respectively provided with a presser foot 4, the presser foot 4 is fixed by a magnet block 3, the middle of the four sides of the upper square frame is provided with a telescopic member 1, the lengths of the four sides of the upper square frame are adjusted by the telescopic member 1, an automatic temperature adjusting mechanism is disposed in the fan 5, and the automatic temperature adjusting mechanism controls the fan 5 to be opened and closed according to the value of the temperature.

In a preferred embodiment, the telescopic member 1 comprises a hinge and a lock catch, the hinge is connected with one end of the joint of the upper frame, the lock catch is connected with the other end of the joint of the upper frame, and the lock catch is connected with different positions of the chain to realize the length adjustment.

In a preferred embodiment, the automatic temperature adjusting mechanism comprises an infrared sensor arranged in the fan, the theoretical basis of temperature measurement of the infrared sensor is blackbody radiation law, the automatic temperature adjusting mechanism comprises an optical system, a detection element and a conversion circuit, wherein the detection element uses a thermosensitive detection element, the temperature of the thermosensitive detection thermistor rises when the thermosensitive detection thermistor receives infrared radiation, the resistance changes, the resistance is changed into an electric signal output through the conversion circuit, the electric signal is weak and needs to be amplified through an amplifier, an LM324 operational amplifier circuit can be adopted, then the analog quantity is transmitted to an A/D analog-to-digital converter to be converted into a digital quantity which can be processed by a singlechip STC89C52, finally, whether the system works or not is controlled through a relay, and when the detected temperature exceeds a threshold value, the fan is controlled to work.

In the use of the present application,

(1) sunlight is prevented from entering as much as possible, and the resistance value of the thermistor in the infrared sensor is changed by the change of the intensity of infrared rays radiated by a human body, so that an electric signal is obtained.

(2) The on-off of the relay can be controlled by the single chip microcomputer. When the temperature is higher than 25 ℃, the singlechip outputs high level, the relay is closed, and the fan starts to work; when the temperature is lower than 25 ℃, the singlechip outputs low level, the relay is disconnected, and the fan stops working.

(3) The bed curtain support can change the length and the width of the support by adjusting the connecting buckle, but the unnecessary trouble caused by overlong chains is avoided.

(4) The presser foot magnet should be of moderate strength, so can prevent that too high intensity bedstead is difficult for moving, also can avoid the too low not firm problem of intensity.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
