Description

A low-power wireless doorbell

technical field

The utility model relates to a doorbell, in particular to a low-power wireless doorbell.

Background technique

The doorbell originated from the decorative knocker on the gate of the ancient big family, which was used to remind the owner of the arrival of guests. With the development of the times and technology, doorbells have changed from simple door knockers and copper bells to modern electronic doorbells. Electronic doorbells are also divided into wired doorbells, wireless doorbells, and video doorbells. Visitors alert the owner with a loud sound of an electronic doorbell that resembles a switch.

With the development of society, more and more users will choose to use doorbell products according to the market consumption level, and the number of users is increasing by 10% every year.

The ordinary doorbells on the market are still in the old and early riser power supply method of stepping down and stabilizing the current. When the product is uninterrupted for 24 hours, it always maintains a state of high energy consumption.

Therefore, there is a need for a doorbell receiving device that can remind the user that a guest is visiting when the doorbell transmitting device is triggered; and at non-triggering time, the doorbell can suspend work and reduce energy consumption.

Utility model content

The technical problem to be solved by the utility model is to overcome the shortcomings of the traditional electronic doorbell, and the purpose of the utility model is to provide a low-power wireless doorbell with the advantage of low standby energy consumption.

The utility model realizes above-mentioned object through following technical scheme:

Aiming at the technical shortcomings of the existing electronic doorbell, a low-power wireless doorbell is redesigned, including a doorbell receiving device that prompts guests to visit the door by sound and a doorbell transmitting device that triggers the doorbell receiving device to emit a sound. The doorbell receiving device is composed of a loudspeaker, a doorbell control module, a high frequency module, a receiving antenna, a power supply control module and a power supply that control the power supply state through the high frequency module; the described loudspeaker, the doorbell control module, the power control module and the power supply are sequentially connected , the high-frequency module is respectively connected with the doorbell control module and the power control module, and the receiving antenna is connected with the high-frequency module. In the standby state, the power control module cuts off the power supply to the doorbell control module, and only supplies power to the high-frequency module; when the high-frequency module receives the trigger signal from the doorbell transmitter from the receiving antenna, the high-frequency module triggers the power supply. The control module supplies power, and controls the doorbell control module to make the speaker sound a prompt.

In order to provide a stable power supply state for the power supply module, a power rectifier bridge module is arranged between the power supply and the power supply control module.

The doorbell transmitting device is composed of a trigger switch, an encoding module, a doorbell signal transmitting module and a transmitting antenna, and the trigger switch, encoding module, doorbell signal transmitting module and transmitting antenna are connected in sequence.

Compared with the prior art, the utility model has the beneficial effects that: the utility model can supply power to the doorbell control module when it needs to work, and suspend the power supply to the doorbell control module when it does not need to work, thereby reducing power consumption the goal of.
