[0010] The circuit board is equipped with connecting ropes, which are connected to a spring and a heating wire respectively, so that the spring is in a compressed state. The heating wire on the circuit board burns off the connecting ropes, and the connecting ropes release the spring, thereby pushing the sprayer so that the liquid inside the sprayer can be sprayed out from the nozzle of the housing.

[0011] Preferably, the mounting base is connected to the housing via a connecting component. A cylindrical protrusion is provided at the center of the mounting base, and an external thread is provided on the outer wall of the cylindrical protrusion to facilitate connection with the connecting component. The mounting base is provided with a groove, which is located on the bottom surface of the mounting base and one end of the groove is connected to the inner wall of the cylindrical protrusion. The bottom surface of the mounting base is provided with multiple first mounting holes. A first fixing rod is provided to cooperate with the first mounting holes to fix the mounting base in the installation position of the spray device used for security.

[0012] Preferably, the connecting assembly includes a connecting rod, a connecting sleeve, a positioning sleeve, and a fixing knob.

[0030] Circuit board 24 is provided with connecting rope 27, which is connected to spring 25 and heating wire 26 respectively, so that spring 25 is in a compressed state. Heating wire 26 on circuit board 24 burns off connecting rope 27, and connecting rope 27 releases spring 25, thereby pushing the sprayer so that the liquid inside the sprayer can be sprayed out from the spray hole 21 of the housing.

[0031] In this embodiment of the invention, preferably, the security spray device is applicable to various occasions such as homes, commercial venues, government agencies, and public facilities. It is installed at a certain height, similar to a regular surveillance camera. The mounting base 1 is used to mount the device body 2. The device body 2 can be connected to external devices via a circuit board 24 to receive signals. The received signal could be a signal indicating theft or robbery by suspicious individuals. The circuit board 24 transmits the received signal to the internal circuit board 24 of the device body 2. The circuit board 24 then controls the heating wire 26 to heat up. When the connecting rope 27 connected to 26 is burned off, the spring 25 connected to the connecting rope 27 changes from a compressed state to a stretched state. At this time, the end of the spring 25 generates an elastic force, which pushes the sprayer to make the liquid in the sprayer spray out from the nozzle 21 of the housing. The sprayer and circuit board built into the housing can be used to fill the liquid in a press-type spray bottle. The elastic force at the top of the spring 25 can push the nozzle of the sprayer to make the liquid in the spray bottle spray out. While meeting the requirements of the liquid in the sprayer, it can also eliminate the need for manual pressing by the user, reduce labor intensity, and realize automatic spraying in certain scenarios.
