Abstract

The utility model discloses a simple and easy doorbell, including the door body, touch face and jingle bell, touch face set up in the external side of door, the jingle bell setting in the internal portion of door, touch face be connected with the touch IC, touch IC be connected with MCU control treater, MCU control treater one end be connected with the jingle bell, the other end is connected with the infrared barrier circuit of keeping away, infrared keep away the barrier circuit be connected with infrared emitting lamp and infrared receipt lamp respectively, the utility model discloses a touch face that sets up, the parasite aircraft that makes the doorbell are unlikely to to expose outdoors, its simple structure is reasonable, and convenient to use is swift, only need the shop front paste a bell button tag paper can, do not worry that the doorbell is destroyed by the people to steal, safer, and need not use the bell button, avoided often using the emergence of damaged condition because of the bell button.

Description

A kind of simple and easy doorbell

Technical field

The utility model belongs to household effects field, particularly relates to a kind of simple and easy doorbell.

Background technology

Doorbell is the common article of existing family, both the inconvenience that guest knocks at the door had been exempted, also the life of neighbours can not be affected because of tap-tap, but, existing doorbell is arranged on outdoors substantially, may be destroyed by some lawless persons or steal, and bell button can damage because often using, very dangerous also impracticable.

Summary of the invention

(1) technical matters that will solve

For solving the problem, the utility model proposes a kind of and need paste a bell button label paper in the shop front, do not worry that doorbell is destroyed by people and steal, safer, and do not need to use bell button, avoid the simple and easy doorbell that damaged condition occurs because bell button often uses.

(2) technical scheme

Simple and easy doorbell of the present utility model, comprises a body, touch face and jingle bell; Described touch face is arranged on the external side of door; Described jingle bell is arranged on a body inside; Described touch face is connected with and touches IC; Described touch IC is connected with MCU control processor; Described MCU control processor one end is connected with jingle bell, and the other end is connected with infrared obstacle avoidance circuit; Described infrared obstacle avoidance circuit is connected to infrared discharge lamps and infrared receiver lamp.

Further, described touch face skin has been sticked bell button label paper.

(3) beneficial effect

Compared with prior art, it has following beneficial effect to the utility model: simple and easy doorbell of the present utility model, by the touch face arranged, makes the handset of doorbell be unlikely to be exposed to outdoors; It is simple and reasonable, convenient to use, only need paste a bell button label paper in the shop front, do not worry that doorbell is destroyed by people to steal, safer, and do not need to use bell button, avoid the generation of damaged condition because bell button often uses.

Embodiment

The simple and easy doorbell of one as depicted in figs. 1 and 2, comprises a body 1, touch face 2 and jingle bell 3; Described touch face 2 is arranged on outside a body 1; It is inner that described jingle bell 3 is arranged on a body 1; Described touch face 2 is connected with and touches IC; Described touch IC is connected with MCU control processor; Described MCU control processor one end is connected with jingle bell, and the other end is connected with infrared obstacle avoidance circuit; Described infrared obstacle avoidance circuit is connected to infrared discharge lamps and infrared receiver lamp.

Wherein, described touch face 2 skin has been sticked bell button label paper.

Power circuit as shown in Figure 3, adopts lithium battery power supply, is transformed the 3.3V voltage of stable output by LDO low pressure difference linearity stabilized voltage supply chip, for MCU control processor, touches circuit, infrared obstacle avoidance check circuit, the power supplies such as loudspeaker.And adopt PJ1134 chip to realize.

Touch circuit as shown in Figure 4, according to capacitance principle, adopts single-button capacitance touch chip, chip theory can realize 5cm distance and touch, touch area by increasing, centre adds medium, improves and touches distance, medium is not being added by reality test, touching area by increasing, can improve and touch distance to about 8cm, adding the medium improving touch sensitivity, the adjustable touch distance of more than 8cm can be realized, and adopt TTP223 chip.

Infrared obstacle avoidance circuit as shown in Figure 5, capacitance touch effect when being to eliminate in door, in addition when door is opened near wall, produces interference, the capacitance touch effect waiting other reasons to cause.Circuit design adopts LM393 voltage comparator to realize, and is regulated keep away barrier distance by potentiometer.

Bell circuit as shown in Figure 6, adopts classical three sound " ding-dong " doorbell module, and loudspeaker realize, and control signal is controlled by triode.

Doorbell synthetic circuit as shown in Figure 7, the stc Single-chip Controlling that have employed one basket of 8 pin realizes, and touches the RST of circuit and infrared obstacle avoidance circuit, is judged by MCU, after identifying processing, controls jingle bell.

Simple and easy doorbell of the present utility model, by the touch face arranged, makes the handset of doorbell be unlikely to be exposed to outdoors; It is simple and reasonable, convenient to use, only need paste a bell button label paper in the shop front, do not worry that doorbell is destroyed by people to steal, safer, and do not need to use bell button, avoid the generation of damaged condition because bell button often uses.

Embodiment recited above is only be described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
