Description

Technical Field

[0001] The utility model relates to the technical field of alarm device equipment, in particular to an SOS alarm. Background Art

[0002] As a device to prevent elderly people living alone from seeking help, the SOS alarm is mainly triggered by the elderly pressing the button on the alarm panel or the pull rope under the alarm. After the alarm detects that the SOS signal has been triggered, it will send out light and sound prompt signals to inform the elderly that the alarm has been successfully triggered. The alarm will communicate with the relevant person in charge through two wireless channels to promptly notify relevant personnel and institutions to reduce personal and property losses.

[0003] Since the SOS alarm requires manual pressing of a button on the alarm panel or a pull rope under the alarm to trigger the SOS signal, and the physical condition of the elderly needs to be taken into consideration, it cannot be set with functions such as anti-mistouch like conventional alarms. For example, patent document number CN210895731U discloses a manual alarm, including an alarm body, the alarm body includes a shell, an alarm unit arranged in the shell and an alarm button arranged on the front side of the shell, and the alarm button is electrically connected to the alarm unit; it also includes a protective auxiliary mechanism, the protective auxiliary mechanism includes a protective shell and an auxiliary knob, the protective shell cover is arranged on the front side of the shell, a threaded through hole is opened on the front side of the protective shell, the auxiliary knob includes a screw and a rotary vane, one end of the screw is vertically arranged at the center of one side of the rotary vane, the other end of the screw passes through the threaded through hole and abuts against the alarm button, and a rotary handle is arranged on the other side of the rotary vane.

[0004] The protective shell in the above patent will hinder the elderly from calling the police immediately. The alarm for elderly users is different from conventional alarms. There is no need to consider the anti-mistouch function, and the elderly's usage experience in dark or other environments must be considered. During use, the following problems may be encountered: 1. In a dark environment, the pull cord or button cannot be seen clearly, which reduces the alarm efficiency; 2. When the alarm light and the speaker used for sound prompts are covered by foreign objects and fail, the user cannot know whether the alarm is successful, which causes user anxiety, etc.; 3. For battery-powered alarms, the elderly may forget to charge the alarm, resulting in the alarm being unusable; 4. Alarms powered by AC power cannot be used during power outages.

The light emitted by the soft light on the lower hanging light panel 200 projects the shadow of the pull rope 120 onto the curtain 300. The warning light on the lower hanging light panel 200 is connected to the light indication module of the control circuit. When the alarm indicator light 130 is on, the warning light on the lower hanging light panel 200 is controlled to light up. A button 160 is also provided on the alarm body 100. The button 160 and the pull rope 120 are connected in parallel to the trigger module of the control circuit. The pull rope 120 is installed at an inclined angle below the battery charging port 110. The upper side of the pull rope 120 is inclined forward. The button 160 is set at a position above the curtain 300 so that the light reflected from the pull rope 120 shines on the button 160.

[0057] Specifically, the screen 300 is tilted forward by 10-30 degrees.

[0058] Working principle: In a dark environment, the soft light of the hanging light board 200 projects the shadow of the pull rope 120 onto the curtain 300, allowing the user to quickly find the pull rope 120 in a dark environment. Compared with directly using light to illuminate the pull rope 120, the projection method makes the position of the pull rope 120 clearer and avoids glare when resting at night.

[0059] In summary, the SOS alarm is configured with a curtain 300 and a hanging light panel 200 respectively arranged at the front and rear ends of the bottom of the alarm body 100, the pull rope 120 is arranged between the hanging light panel 200 and the curtain 300, the hanging light panel 200 is connected to a photosensitive sensor, and the light from the soft light of the hanging light panel 200 in a dark environment projects the shadow of the pull rope 120 onto the curtain 300, so that the user can quickly find the pull rope 120 in a dark environment. Compared with directly using light to illuminate the pull rope 120, the projection method makes the position of the pull rope 120 clearer and avoids glare when resting at night.

[0060] The SOS alarm is configured with a warning light in the lower-hanging light panel 200, which is connected to the same light indication module as the warning indicator light 130. When the warning indicator light 130 is covered or fails, the warning light on the lower-hanging light panel 200 can enhance the warning effect.

[0061] The SOS alarm transmits the alarm information to the background wirelessly by setting at least two modules with wireless communication function, and provides the ability to use redundant channel communication when one of the communication channels is limited, so as to accurately and timely guide relevant personnel to take measures to protect personal and property safety.

[0062] The SOS alarm device provides a battery charging port 110, a built-in battery and a mains power supply interface to avoid the alarm device being unusable when charging is forgotten or when there is a power outage, and uses a low-power design solution to effectively increase the standby time.
