Definitions

  • the present invention relates to an alarm device and, especially, to an alarm device with a switch or other devices which can be triggered by a manual touch in an abnormal condition.
  • US 4,857,678 A discloses an electrical switch with contact carrier means for sliding in a first direction, a housing for slidably supporting the carrier means, terminal means mounted on the housing, a contact mounted on the carrier means for contacting the terminal means, and a plunger mounted on and slidable with the contact carrier for moving in a second direction substantially perpendicular to the first direction to cause said contact to engage or disengage the terminal means.
  • EP 1 113 472 A1 discloses an electrical switch comprising two fixed contacts in a housing, a tripping member which can deform elastically in a direction perpendicular to the bottom of the housing, and an actuation pusher mounted so as to slide in a lateral direction parallel to the bottom of the housing, so as to convert the actuation force exerted on the pusher into a perpendicular tripping force.
  • Modern manual alarm devices have to be usable in various harsh environments. For example, in the case of a high temperature, the plastic components of a manual fire alarm device when heated tends to creep, and the direction of the creeping deformation is usually parallel with the pressing direction of the manual alarm device, and then, even if there is no positive triggering on the alarm button, the alarm device may sound an alarm spontaneously, then the phenomenon of a false alarm occurs, which seriously affects the reliability of the manual alarm devices used at high temperatures.
  • the object of the present invention is to provide a manual alarm device, which can work accurately and reliably regardless of the severe environments such as high temperature, sand storms, rains and snows, etc.
  • the present invention intends to provide a manual alarm device, and for it to sound an alarm, the pressing direction by the operator is perpendicular to the triggering direction of the switch, thus avoiding a false alarm caused by the creeping deformation of the plastic components at a high temperature.
  • the operating element can return to the plane which is in its state of monitoring after an operator has completed a pressing operation for sounding an alarm, so that even if in the state for sounding an alarm, the manual alarm device can also achieve good dust- and waterproof effects.
  • the present invention provides a manual alarm device, and since the pressing direction is perpendicular to the direction of triggering the switch for sounding an alarm, the movement of the switch in the triggering direction when an operator presses the alarm device can be further used to produce a distinct visual change compared with the state of monitoring to prompt the user that the alarm device has been put in the state for sounding an alarm, which further improves its reliability and safety when being used.
  • a manual alarm device comprising:
  • the manual alarm device comprises a circuit board assembly with a switch unit thereon; an operating element which can be pressed along a pressing direction by an operator, including a contact member which can come into contact with the switch unit; and a base in which the circuit board assembly and the operating element can be disposed; the operating element further comprises a pair of lugs which are arranged on both sides of the end of the operating element away from the contact member; the base is further provided with a pair of guide rails, and the lugs are respectively disposed in each corresponding guide rail; and a locator is further disposed between the end of the operating element close to the lugs and the base corresponding thereto, so that when the operating element is pressed, the locator can drive the operating element to move in a direction perpendicular to the pressing direction, thus bringing the contact member on the operating element to separate from or to come into contact with said switch unit.
  • the locator disposed between the end of the operating element close to the lugs and the base corresponding thereto is an elastic element with both ends respectively fixed on the lugs of the operating element and a protruded middle part bearing against a position of said base, which position is opposite to the end of said operating element close to the lugs.
  • the locator can also be a spring, which spring is pressed between the end of the operating element close to the lugs and a position on said base, which position is opposite to the end of the operating element close to the lugs.
  • the manual alarm device of the present invention further comprises an elastic member with one end being disposed on the base and the other end being pressed against the operating element, so as to enable the operating element, after the pressing on the operating element stops, to return to the same plane as it was when not being pressed.
  • the elastic member can also be pushed against the operating element via an end cap.
  • the operating element is further provided with a transparent hole, through which said circuit board assembly can be partly displayed.
  • the circuit board assembly can be provided with a color sign on the position corresponding to the transparent hole of the operating element, and after the operating element is moved under the drive of the locator, the color sign can be shown through the transparent hole; alternatively, the circuit board assembly can be covered by a circuit board assembly cover, a color sign is disposed on the surface of the circuit board assembly cover towards the operating element, and after the operating element has moved under the drive of the locator, the color sign can be shown through the transparent hole.
  • the manual alarm device further comprises an upper cover which is disposed together with the base, and a window is provided in the middle of the upper cover for the operating element to be pressed.
  • the color sign on the circuit board assembly or the circuit board assembly cover can be shown by the window in the middle of the upper cover through the transparent hole on the operating element.
  • the action direction of the operating element is parallel with the triggering direction of the switch unit, and the creeping direction of the operating element at a high temperature is often parallel with the action direction of the operating element too, therefore if the creeping direction is the same as the triggering direction of the switch unit, a false alarm may occur.
  • the manual alarm devices provided in the present invention since the triggering direction of the switch unit is perpendicular to the creeping direction of the operating element, i.e. the creeping of the operating element cannot cause the switch element's position to change in the triggering direction, thus avoiding a false alarm.
  • the operating element is in the same plane before and after sounding an alarm by means of the action of the elastic member, therefore it can effectively prevent water and dust from entering the manual alarm device.
  • Fig. 1 is an exploded illustrative view of the structure of a manual alarm device of the present invention, which comprises a base 10, a circuit board assembly 20 and an operating element 40.
  • the base 10 has two opposite side walls 11, and guide rails 12 (only one is shown in Fig. 1 ) corresponding to each other which are respectively disposed in the two opposite side walls 11.

  • the lugs 44 of the operating element 40 are provided in the guide rails 12 of the base 10.
  • Fig. 3 illustrates a perspective exploded view of another particular embodiment of the manual alarm device in the present invention, and the parts in this figure with the same or similar structures and the same functions as those in Fig. 1 will not be explained redundantly.
