Abstract
A door close reminder is provided, which is composed of a power supply, a power switch, a buzzer, a baffle, an infrared transmitter, an infrared receiver and a delay circuit. The utility model is equipped with the infrared transmitter and the infrared receiver respectively on left and right sides of the door; the baffle is arranged on a door panel; the infrared transmitter, the receiver and the baffle are on the same level; the buzzer is equipped on one side of the infrared receiver; the infrared receiving circuit is connected with a buzzer circuit through the delay circuit. The utility model not only can effectively reduce the potential safety hazards from the door not closed well, but also has the advantages of simple structure and setting time delay reminding at random, etc. according to the practical situation.
Description
Technical field
The utility model relates to a kind of class anti-theft device, specifically a kind of reminiscences of closing the door with delay function.
Background technology
Forget when being easy to go out along with the busy people of the quickening of city life rhythm and close the door that the elderly closes the door owing to the memory function decline also is easy to forget in addition, so article are stolen, the situation of property loss happens occasionally.People have also designed some alarm sets of closing the door at this phenomenon, but also have some shortcomings, such as complex structure, and can only instant alerts etc.
Summary of the invention
The purpose of this utility model is exactly at the weak point in the above-mentioned background technology, provides a kind of simple in structure and have a reminiscences of closing the door of delay function.
The purpose of this utility model realizes by following technical measures: the alarm set of closing the door, by power supply, power switch, hummer, baffle plate, fired infrared receiver and delay circuit are formed, and the reminiscences of closing the door described in the utility model is in the left and right sides of door infrared emission and infrared receiving device to be housed respectively, be provided with a baffle plate on door-plate, infrared launcher, receiving trap and baffle plate are in same horizontal level.Turn on the power switch, power supply is powered to infrared launcher, the emission infrared light.Close the door at ordinary times under the state, the infrared light that sends is blocked by the baffle plate on the door-plate, and the receiving trap of opposite side can't receive.When door was opened, baffle plate no longer was in and transmits and receives between the device, and receiving trap just can receive infrared light.
In infrared receiving device one side hummer is housed.Infrared receiving circuit is connected with buzz circuit by delay circuit.After infrared receiving device receives infrared light, thereby because the change of self both end voltage value triggers delay circuit work, behind predefined delay time, delay circuit is connected buzz circuit, is sounded by hummer at last, and reminds people is closed the door.
The utility model can not only effectively reduce Men Wei and shut the potential safety hazard of bringing, and also has simple in structurely, and advantages such as time delays prompting can be set arbitrarily according to actual conditions.
Description of drawings
Fig. 1 is the close the door assembly structure synoptic diagram of reminiscences of the utility model.
Fig. 2 is the close the door circuit block diagram of reminiscences of the utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in Figure 2, a kind of alarm set of closing the door is by power supply, power switch, hummer 4, baffle plate 3, infrared launcher 1 receiving trap 2 and delay circuit are formed, the utility model is in the left and right sides of door infrared launcher 1 and infrared receiving device 2 to be housed respectively, be provided with a baffle plate 3 on door-plate 5, infrared launcher 1, receiving trap 2 and baffle plate 3 are in same horizontal level, in infrared receiving device 2 one sides hummer 4 are housed.Infrared receiving circuit is connected with buzz circuit by delay circuit.
The luminotron material that adopts in the infrared emission circuit is generally arsenic potassium semiconductor, infrared receiving tube available light electric diode or triode.The simplest method of delay circuit is to realize triggering time-delay with RC circuit and one 555 integrated circuit, and resistance wherein adopts variable resistor, realizes the adjustability of time-delay.
