In the description of the present invention, it should be noted that if the terms "upper", "lower", "side", "bottom", "top", "center", "outer", etc., the orientation or The positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, Therefore, it cannot be understood as a limitation to the present invention. In the description of the present invention, it should be noted that, unless otherwise clearly specified and defined, those of ordinary skill in the art may understand the specific meaning of the above terms in the present invention in specific circumstances.

As shown in FIG. 1, the present invention provides a new type of grip-type automatic control fire-extinguishing fire extinguisher. The fire extinguisher is generally in the shape of a grenade and includes a fire-extinguishing bomb body. The fire-extinguishing bomb body includes a central shell 1. , The lower end of the central shell 1 is provided with an outer shell 2, a pyrotechnic agent 3 and an electric igniter 4 and a controller for detonating the pyrotechnic agent 3 are arranged inside the central shell 1, the controller is connected to the electric igniter 4, the outer shell 2 and the central shell There is a fire extinguishing powder 5 between 1, and it also includes an external terminal and a command receiver. The external terminal is used to send a fire start signal command. The command receiver is connected to the controller. The command receiver is used to receive a fire start signal command sent by an external terminal. The controller is used to turn on the electric starter 4 according to the start signal received by the command receiver to prepare to detonate the pyrotechnic agent 3.

Among them, the command receiver receives the fire signal command sent by the external terminal, which is mainly realized through wireless wifi or Bluetooth. The controller can use plc programmable controllers that are universal on the market, such as the GEI type of GE, the S7-200 of Siemens of Germany, and the F series of Mitsubishi Electric. The external terminal can be a wireless remote control, a mobile phone, a laptop, or an immovable control platform.

It should be particularly noted that in the embodiment shown in FIG. 1, the center shell and the outer shell are both cylindrical, but the center shell and the outer shell are not limited to the cylindrical shape, but can also be other shapes, such as the center shell can be a rectangular parallelepiped The shape may also be abnormity, the upper end is cylindrical or cuboid, and the lower end is spherical; similarly, the shell may be cuboid or spherical.

More preferably, the external terminal includes an alarm prompt unit. When the distance detection unit detects that the control distance is less than or equal to the preset safety distance, the alarm prompt unit performs an alarm prompt. The specific control logic is as follows. The distance detection unit first starts to detect the control distance between the external terminal and the body of the fire extinguishing bomb. When the control distance is greater than the preset safety distance, the external terminal is far away from the body of the fire extinguishing bomb. At this time, the fire extinguishing bomb can be normally detonated through the external terminal. When the control distance is less than or equal to the preset safety distance, the external terminal is close to the body of the fire extinguishing bomb. At this time, the fire extinguishing bomb cannot be detonated through the external terminal, and at the same time, the alarm prompt unit gives an alarm prompt. The alarm prompt unit may include one or more of light alarm, voice alarm, and odor alarm. Preferably, the battery 6 for power supply is also included, and the command receiver and the controller are built in the battery 6 and electrically connected to each other.
