Technical Field

The utility model belongs to the technical field of the electron.

Background

Because the common electronic intelligent blind guiding stick is not provided with a specific alarm device, when the electronic intelligent blind guiding stick falls onto the ground carelessly, a user needs to continuously search on the ground, and a lot of inconvenience is brought to the user.

For the research of the blind guiding rod alarm device, as the patent application numbers: 200820053860.1, the invention is a utility model patent named as blind guiding stick alarm device, which starts an alarm when the blind guiding stick falls down to the ground, and prompts the user about the position of the blind guiding stick, thereby bringing great convenience to the user; however, the alarm device of the blind guiding rod can be started as long as the blind guiding rod is in a horizontal state, and when a user normally uses the blind guiding rod, the blind guiding rod cannot be prevented from being in the horizontal state, so that false alarm is easily caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the blind stick alarm device arouses the false alarm easily for current electron intelligence leads, provides an electron intelligence leads blind stick and falls to the ground alarm device.

The utility model relates to an electronic intelligent blind guiding rod landing alarm device, which comprises a shell, a self-locking pressure switch, a buzzer, a storage battery and a clapboard;

the shell is of a cylindrical structure with an opening at one end, the cylindrical side wall and the bottom surface are provided with communicated air bag cavities, and the cylindrical side wall is provided with a hand-held hollow part;

the baffle plate is arranged in the shell and divides the shell into an accommodating cavity with an opening at one end and a closed circuit protection cavity, and the electronic intelligent blind guiding rod is nested in the accommodating cavity;

auto-lock pressure switch, bee calling organ and battery set up respectively in the circuit protection intracavity, and auto-lock pressure switch's trigger end and the gasbag chamber intercommunication of shell, and auto-lock pressure switch electricity connects the positive pole of one end and battery to link to each other, and the negative pole of battery links to each other with bee calling organ's negative pole feed end, and bee calling organ's positive pole feed end links to each other with auto-lock pressure switch electricity connects the other end.

An electronic intelligence leads blind stick and falls to ground alarm device's theory of operation do: lead blind stick nestification in the holding intracavity with electronic intelligence, after this alarm device that falls to the ground, when shell and ground contact, because electronic intelligence leads blind stick's action of gravity can produce pressure, this pressure makes the action of auto-lock pressure switch through the conduction in gasbag chamber, auto-lock pressure switch converts the normally open state into normally closed state, bee calling organ constitutes the return circuit this moment and sends the buzzing sound and reports an emergency and asks for help or increased vigilance, after this alarm device that falls to the ground that the user picked up the blind stick of holding electronic intelligence, press auto-lock pressure switch's reset button, auto-lock pressure switch converts normally closed state into normally open state, bee calling organ is in the off state this moment, bee calling organ stops to send the.

The beneficial effects of the utility model are that the shell is equipped with holds the shape fretwork, as long as guarantee that the exact appearance of holding or hold the shell after not continuously press the shell, bee calling organ all can not report an emergency and ask for help or increased vigilance, and because auto-lock pressure switch has the auto-lock effect, bee calling organ can not only sound in the twinkling of an eye that falls to the ground, bee calling organ can continuously keep after reporting an emergency and ask for help or increased vigilance the state, just can finish reporting an emergency and asking for help or increased vigilance the state until the.

Detailed Description

The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 4, and the electronic intelligent blind guiding rod floor alarm device of the embodiment comprises a shell 1, a self-locking pressure switch 2, a buzzer 4, a storage battery 5 and a partition plate 6;

the shell 1 is of a cylindrical structure with an opening at one end, the cylindrical side wall and the bottom surface are provided with communicated air bag cavities, and the cylindrical side wall is provided with a hand-held hollow part; the hand-held hollow part is convenient for ensuring that a user directly contacts with the electronic intelligent blind guide rod when holding the electronic intelligent blind guide rod, so that the hand of the user is prevented from directly contacting with the shell 1; the air is filled into the air bag cavity;

the partition plate 6 is arranged in the shell 1 and divides the shell 1 into an accommodating cavity with an opening at one end and a closed circuit protection cavity, and the electronic intelligent blind guiding rod is nested in the accommodating cavity to ensure that the shell 1 can be contacted with the ground and change the pressure of gas in the air bag cavity when the electronic intelligent blind guiding rod falls to the ground; the electronic intelligent blind guiding rod is nested in the accommodating cavity to ensure that the electronic intelligent blind guiding rod is in close contact with the shell 1, and the electronic intelligent blind guiding rod is prevented from being separated from the shell 1 in the falling process;
