Technical Field

The invention relates to an automatic doorbell device based on a piezoelectric ceramic piece, and belongs to the field of building materials.

Background

With the rapid development of modern science and technology, scientific and technological products change the life of modern human beings more and more obviously, and the quality of life of people is greatly improved, especially the intelligent control related to the electronic information technology which is developed at a high speed at present is permeated into the aspects of life of people. Taking an intelligent home as an example, the core technology of the intelligent home system is to organically integrate a modern intelligent control technology and a daily life home, and finally realize the home intelligence. The automation of the doorbell device is part of a smart home. At present, the home and abroad doorbell devices are mostly controlled by manual switches, and the operation process is as follows: when the pedestrian walks to the gate, press doorbell control switch, the doorbell warning reminds the people in the room to open the door to get into in the room. But it is not good that it is not good to take full thing or light evening when the pedestrian both hands, is not convenient for press doorbell control switch's the condition under, will unable warning indoor people open the gate, consequently design and produce automatic doorbell device and be life reality needs.

Through the search of the prior art documents, the automatic doorbell detection device mentioned in the patent of 'a contactless automatic doorbell detection device' written by foreign language primary school in the development area of the Zhengzhou high and new technology industry can realize the automatic alarm of the doorbell through a human body induction sensor under the condition that a doorbell control switch is not required to be manually pressed, so that people in a room can open the door. However, the human body induction sensor is adopted in the patent, so that the human body induction sensor is easily interfered by an external electromagnetic field, the working stability and reliability of the human body induction sensor are reduced, an external power supply is required to normally work, and the structural complexity is increased.

Disclosure of Invention

The invention aims to provide an automatic doorbell device based on a piezoelectric ceramic piece, aiming at the defects of the prior art. The device make full use of piezoceramics material have malleation electric effect characteristic, walk in piezoceramics piece top promptly before the gate when the pedestrian, the gravity of pedestrian self will be applyed for piezoceramics piece and last and regular pressure, the piezoceramics piece of nine series connections produces the electromotive force and passes through electric energy output wire, thereby fixed value resistance and doorbell formation return circuit produce electric current, final doorbell sounds, remind indoor people to open the gate, realize the full automatization that the doorbell sounds, people's daily life has been made things convenient for, very big improvement furniture equipment's intellectuality and hommization.

In order to achieve the purpose, the invention adopts the following technical scheme:

an automatic doorbell device based on a piezoelectric ceramic piece comprises a fixed value resistor, an electric energy output lead, a doorbell, a gate, a pedestrian, the piezoelectric ceramic piece, a series lead and an insulating piece.

The fixed value resistor is arranged in the wall, one end of the fixed value resistor is connected with the piezoelectric ceramic, and the other end of the fixed value resistor is connected with the doorbell.

The electric energy output wire is also arranged in the wall and below the ground, and the fixed value resistor, the doorbell and the piezoelectric ceramic piece are connected in series to form a loop.

The doorbell is installed right above the door, and people inside the house can be reminded of opening the door conveniently.

The piezoelectric ceramic piece total is nine, and nine piezoelectric ceramic pieces of establishing ties are divided into three-layer and are piled up from top to bottom, and each layer contains three piezoelectric ceramic pieces of establishing ties.

The insulating sheet is assembled in the piezoelectric ceramic sheet gap between layers.

The working principle of the invention is as follows: when the pedestrian walks in piezoceramics piece top promptly before the gate, thereby pedestrian's self gravity will exert lasting and regular pressure for piezoceramics piece, according to the positive piezoelectric effect that piezoceramics material has, the electromotive force that nine piezoceramics pieces of establishing ties produced and through electric energy output wire, thereby constant value resistance and doorbell formation return circuit produce the electric current, final doorbell sounds, remind indoor people to open the gate, realize the full automatization that the doorbell sounds, the daily life of people has been made things convenient for, very big improvement furniture equipment's intellectuality and hommization.

The invention has the beneficial effects that:

the most core innovation of the invention is that nine piezoelectric ceramic pieces are uniformly divided into three layers and assembled below the ground by utilizing the positive piezoelectric effect of the piezoelectric ceramic material, when a pedestrian walks over the piezoelectric ceramic pieces, the gravity of the pedestrian applies continuous and regular pressure to the piezoelectric ceramic pieces to generate electromotive force, and finally current is generated to drive the doorbell to work, thereby avoiding the defect that an external power supply needs to be added, and enabling the whole device to be simple and efficient.
