Abstract

The utility model discloses a device for reminding people leaving home of carrying keys. The device comprises a tray, a spring, a base, a gravity switch, a sound system, a power supply and an induction switch, wherein the gravity switch and the induction switch are normally open and connected with the sound system and the power supply to form a series circuit; the spring is sleeved on a straight pole at the bottom end of the tray and positioned between the tray and the base to form an elastic supporting structure; and the lower end of the straight pole of the tray is linked with the gravity switch. When a host goes out and reaches the induction zone set by the induction switch, if keys and other articles in the tray are still not taken away, the induction switch forms a loop together with the sound system and the power supply by the aid of the conducted gravity switch, so that the sound system is powered on and sounds, and the sound is a voice prompt sound. The device provided by the utility model can promptly remind the host to carry the keys and other articles before going out, thereby effectively preventing the host from forgetting to carry the keys before going out. The device is suitable for families of not only the aged but also the broad office workers.

Description

Carry the key reminiscences before going out

Technical field

The utility model relates to a kind of civilian small electric apparatus, and specifically, the utility model carries the key reminiscences before relating to a kind of going out.

Background technology

Along with social progress and development, people's housing condition is greatly improved, and the people who lives the commercial house is more and more.The present age, the commercial house generally was a building, and the separate space of oneself is arranged after every household is gone out, and had good privacy.Supporting gate, existing goods room generally is the irony antitheft door, and dwelling house is set up antitheft door and improved security greatly.China has got into aged society, and pure old man family is a lot, because older being losing one's memory, many old men have to go out and leave behind the experience of key.The old man who lives the commercial house gos out and leaves behind key, can cause very big life trouble and economic loss, causes some security incidents because of can not in time opening the gate sometimes.In addition, reason such as young man is fast because of rhythm of life, working pressure is big is gone out and also can be left behind article incidents such as key or mobile phone.Carry the key reminiscences in front of the door as if setting out, can avoid this type of problem to take place, greatly be convenient for people to life through timely voice reminder in inboard, every family gate.

The utility model content

The old man that the utility model is primarily aimed at the commercial house gos out and leaves behind the problem that key brings the life trouble, propose a kind of simple in structure, reliable, automaticity is high, cheap carries the key reminiscences before going out.

The utility model is realized technical goal through following technical proposals.

Carry the key reminiscences before going out, it comprises pallet, spring, base, gravity switch, sound system, power supply and inductive switch.Said gravity switch and inductive switch are for often opening shape, and both and sound system, power supply connect and compose series circuit.Its improvements are: said pallet bottom is provided with the outer pocketed springs of straight-bar; Spring constitutes the elasticity load-carrying members between pallet and base; Straight-bar lower end interlock gravity switch, pallet sinks to facilitating gravity switch to be in conducting state after the loading, facilitates gravity switch to break off otherwise pallet rises.Said inductive switch is facing to the gate inside casing, and an end connects weight power switch, and the other end connects power supply; Someone impels inductive switch closed through producing induction current; Otherwise be in the disconnection shape, under gravity switch and inductive switch complete closure situation, form the loop, sound system gets the electric sound equipment sound that sends.

It is voice suggestion sound that above-mentioned sound system gets the electric sound equipment sound that sends.

When the utility model is practical, have following benefit:

1, under gravity switch and the full conducting situation of inductive switch, send prompting sound through sound system, ask owner to go out and be with key, prompting sound is accurate, reduces the trouble of going out and not being with key and causing;

2, normal open circuit, power consumption is few;

3, simple series circuit cooperates with physical construction, and is easy to manufacture, cheap;

4, night illegal invasion person had warning function.

Description of drawings

Fig. 1 does not put article such as key in the utility model pallet, gravity switch is in off-state, and inductive switch does not have power supply inoperative, and sound system does not send prompting sound.

Fig. 2 is equipped with article such as key in the utility model pallet, gravity switch is in conducting state, and inductive switch is in off-state, and sound system does not send prompting sound.

Fig. 3 is equipped with article such as key in the utility model pallet, gravity switch and inductive switch are in conducting state, and sound system sends prompting sound.

Embodiment

According to accompanying drawing and combine embodiment, the utility model is described further below.

Carry the key reminiscences before shown in the drawings the going out; It is a kind of electromechanical integrated product; Comprise pallet 1, spring 2, base 3, gravity switch 4, sound system 5, power supply 6 and inductive switch 7 said gravity switchs 4 and inductive switch 7 for often opening shape, both and sound system 5, power supply 6 connect and compose series circuit.Pallet 1 bottom is provided with the outer pocketed springs 2 of straight-bar, and spring 2 constitutes the elasticity load-carrying members between pallet 1 and base 3, the straight-bar lower end interlock gravity switch 4 of pallet 1.The utlity model has three kinds of duties, at first is as shown in Figure 1 under the normal condition, does not put article 8 such as key in the pallet 1, and gravity switch 4 is in off-state, and inductive switch 7 does not have power supply inoperative, and sound system does not send prompting sound.Secondly duty is as shown in Figure 2, and the owner who goes home is placed to article such as key 8 in the pallet 1, sinks to making the gravity switch 4 of interlock be in conducting state after pallet 1 load-carrying, and this moment, inductive switch 7 was in off-state, and sound system does not still send prompting sound.Last a kind of duty is as shown in Figure 3; Arrive inductive switch 7 when owner gos out and set induction region; Be inside casing place, gate, if article 8 such as key are still in pallet 1, inductive switch 7 weight power switches 4 and sound system 5, power supply 6 formation loops by conducting; Make sound system 5 get the electric sound equipment sound that sends, the utility model middle pitch sound is a voice suggestion sound.Make owner before going out to go out, take article 8 such as key earlier through timely prompting, effectively avoid going out to forget band key and so on thing and take place.The utility model uses except being fit to the Old Age Homes, also is fit to numerous working clans family and uses.
