Abstract
The utility model relates to a dehumidification system, in particular to an ultrasonic dehumidification assembly comprising a piezoelectric ceramic ultrasonic transducer. The ultrasonic dehumidification assembly comprising the piezoelectric ceramic ultrasonic transducer comprises an article to be dehumidified, the piezoelectric ceramic ultrasonic transducer and a driving circuit, wherein the piezoelectric ceramic ultrasonic transducer is fixedly connected to the article to be dehumidified and is connected with the output end of the driving circuit; the input end of the driving circuit is connected with an external power supply; and the frequency of a high-frequency power supply which is generated by the driving circuit is matched with that of the piezoelectric ceramic ultrasonic transducer. By the ultrasonic dehumidification assembly comprising the piezoelectric ceramic ultrasonic transducer, mist or water on the surface of the article to be dehumidified such as a windshield or a rear view mirror of an automobile can be effectively and quickly removed through ultrasonic waves.
Description
Technical field
The present invention relates to a kind of dehumidification system, particularly relate to a kind of ultrasonic dehumidifying assembly that comprises piezoelectric ceramic ultrasonic transducer.
Background technology
When driving in the rainy day, existing automobile need open rain brush for driving safety.In addition, owing to the weather reason, sometimes vehicle glass particularly front windshield can haze, if demist in time just might influence driving safety.Existing defogging method comprises that the air conditioner ventilating system that uses automobile carries out demist or carries out demist through electro heat, and only uses rain brush can not reach the purpose of demist.Also have, when meeting with heavy rain or heavy rain, only use rain brush still can not in time remove the rainwater on the front windshield, thus the potential safety hazard of causing.
Need a kind of auxiliary (water) the wet system that removes that when meeting with heavy or torrential rain, can in time remove rainwater on glass.This dehumidification system can be removed fog on glass when needed fast.
Summary of the invention
To prior art, the invention provides a kind of ultrasonic dehumidifying assembly that comprises piezoelectric ceramic ultrasonic transducer.Described ultrasonic dehumidifying assembly can direct mount on front windshield or back mirror such as but not limited to automobile.Open said ultrasonic dehumidifying assembly when needed, can remove the fog on the vehicle glass fast, and can when meeting with heavy rain or heavy rain, can in time assist the rainwater of removing as on front windshield, the back mirror, guarantee driving safety through the super sonic that produces.
A kind of ultrasonic dehumidifying assembly of piezoelectric ceramic ultrasonic transducer that comprises among the present invention comprises: article to be dehumidified, piezoelectric ceramic ultrasonic transducer, driving circuit; Wherein said piezoelectric ceramic ultrasonic transducer is fixedly connected on the described article to be dehumidified; Described piezoelectric ceramic ultrasonic transducer is connected with the mouth of driving circuit; The input end of described driving circuit is connected with external power supply, and the frequency of the high frequency electric source of said driving circuit generation and the frequency adaptation of piezoelectric ceramic ultrasonic transducer.
Described piezoelectric ceramic ultrasonic transducer and driving circuit can adopt known piezoelectric ceramic ultrasonic transducer and driving circuit.The frequency of piezoelectric ceramic ultrasonic transducer depends primarily on the material of the piezoelectric ceramic piece that is adopted, and the frequency of the oscillating circuit of the driving piezoelectric ceramic ultrasonic transducer of being selected for use should be suitable with the frequency of piezoelectric ceramic ultrasonic transducer.
In concrete embodiment of the present invention, described article to be dehumidified are the front windshield or the back mirror of automobile, or both have both at the same time.
Described piezoelectric ceramic ultrasonic transducer can adopt adhesive agent to be bonded on described shield glass or the back mirror.Also can adopt other physical construction such as screw to be detachably fixed on described shield glass or the back mirror.
Described external power supply can be the power supply of free voltage, as but be not limited to automobile with direct supply such as 12V power supply.
Should be known in that the ultrasonic dehumidifying assembly that comprises piezoelectric ceramic ultrasonic transducer among the present invention can be used for the occasion that other need dehumidifying (water), like the front windshield of aircraft etc.
The described ultrasonic dehumidifying assembly of piezoelectric ceramic ultrasonic transducer that comprises can have switch, through switch connection or disconnecting external power supply, thereby drives or stops described ultrasonic dehumidifying assembly.
The ultrasonic dehumidifying assembly that comprises piezoelectric ceramic ultrasonic transducer among the present invention can be removed fast through super sonic effectively and wait to dehumidify article such as shield glass or surperficial fog or the low amounts of water of back mirror; And can when meeting with heavy rain or heavy rain, remove a large amount of rainwater on the shield glass by auxiliary rain brush, guarantee driving safety.
Description of drawings
Fig. 1 is a kind of structural representation that comprises the ultrasonic dehumidifying assembly of piezoelectric ceramic ultrasonic transducer of the present invention.
The specific embodiment
For more being expressly understood the present invention, combine accompanying drawing that the present invention is described further at present.Should be appreciated that the specific embodiment of the present invention described in the accompanying drawing is merely explanation usefulness of the present invention, is not construed as limiting the invention.Protection scope of the present invention is limited appending claims.
Fig. 1 shows a kind of structural representation that comprises the ultrasonic dehumidifying assembly of piezoelectric ceramic ultrasonic transducer of the present invention.As shown in Figure 1, the ultrasonic dehumidifying assembly 10 that comprises piezoelectric ceramic ultrasonic transducer among the present invention is used to the front windshield demist of automobile or dewaters.Described ultrasonic dehumidifying assembly 10 comprises shield glass 1, be bonded in the piezoelectric ceramic ultrasonic transducer 2 on the shield glass 1 and be used to drive the driving circuit 3 of piezoelectric ceramic ultrasonic transducer 2.Driving circuit 3 designs according to the frequency of piezoelectric ceramic ultrasonic transducer 2, and makes the frequency of driving circuit 3 and piezoelectric ceramic ultrasonic transducer 2 adaptive.The mouth of driving circuit 3 is connected with piezoelectric ceramic ultrasonic transducer 2, and the input end of driving circuit 3 is connected through the switch (not shown) with automobile 12V direct supply.
When hazing (as in time autumn and winter) at shield glass; Can pass through the switch connection automobile power source, driving circuit 3 will be imported power supply and handle the power supply that obtains the adaptive frequency of needed and piezoelectric ceramic ultrasonic transducer 2 and supply with piezoelectric ceramic ultrasonic transducer 2 through its mouth.Piezoelectric ceramic ultrasonic transducer 2 converts electric energy to corresponding super sonic, and super sonic then becomes water into ultramicron, then by rapid evaporation, thereby reaches the purpose of removing fog.
Based on description to the preferred embodiment for the present invention; Should be clear; Be not limited only to the specific detail set forth in the top specification sheets the present invention that appending claims limited, what do not break away from aim of the present invention or scope possibly reach the object of the invention equally to many conspicuous changes of the present invention.
