In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0045] To reduce costs and facilitate installation, see Figure 1-Figure 3The present embodiment provides an electrically activated fire extinguishing device, comprising a shell 1, a temperature detection element 2, a trigger assembly, and a start assembly 3; the upper portion of the outer shell 1 is clamped with a temperature detection element 2 for detecting the ambient temperature, and the trigger assembly and the start assembly 3 are installed in the shell 1; the temperature detection element 2 is a temperature-sensitive glass ball or a fusible metal ball. For example, when it is a temperature-sensitive glass ball, the release temperature of the temperature-sensitive glass ball is preset according to the scene requirements. When the ambient temperature reaches the release temperature, the temperature-sensitive glass ball bursts, and the trigger assembly triggers the start assembly 3 to start to extinguish the fire; wherein the upper portion of the trigger assembly extends out of the top surface of the shell 1 to wrap the lower portion of the temperature detection element 2, so that the temperature detection element 2 applies downward pressure to the trigger assembly (at this time, the start element is in a closed state), and when the temperature detection element 2 reaches the preset release temperature, it bursts, so that the trigger assembly moves upward to achieve conduction with the start assembly 3 for fire extinguishing. In this process, the trigger assembly moves upward along the shell 1 after decompression, and then triggers the start assembly 3 to open for fire extinguishing operation.

[0046] In a specific embodiment, see Figure 1-Figure 4 The trigger assembly includes a movable part 4, an elastic part 5, a piezoelectric ceramic 6, and a wire 7; the upper part of the movable part 4 extends out of the shell 1 to wrap the lower part of the temperature detection element 2, and the elastic part 5 is sleeved on the lower part of the movable part 4, and one end abuts against the lower part of the movable part 4, and the other end abuts against the base 11 of the shell 1. The elastic part 5 restores its elastic length through the bursting of the temperature detection element 2, and drives the movable part 4 to move upward to trigger the piezoelectric ceramic 6 to close. Preferably, the elastic part 5 is a compression spring, which is compressed when the device is not turned on. The compression spring is in a compressed state, and when the temperature detection element 2 senses that the external temperature is the preset release temperature, it bursts. At this time, the compression spring is decompressed and restores its elastic length, and then lifts the movable part 4 to move upward to trigger the piezoelectric ceramic 6 to close; the piezoelectric ceramic 6 is arranged on the inner wall of the shell 1 and is connected to the starting component 3 through the wire 7. After closing, the piezoelectric ceramic 6 transmits current to the starting component 3 through the wire 7 to start the starting component 3 to extinguish the fire; the starting component 3 is arranged in the movable part 4 and is coaxial with it.

On the upper end surface, the elastic member 5 is sleeved outside the hollow column 44, and the lower part of the hollow column 44 is located at the base 11 of the shell 1, so that the upper end of the elastic member 5 abuts against the lower end surface of the movable guide plate 43, and the lower end abuts against the base 11 of the shell 1. When the fire extinguishing device is not activated, the elastic member 5 is in a compressed state. When the fire extinguishing device is to be activated, the elastic member 5 restores its elastic length to push the movable guide plate 43 to move upward to trigger the piezoelectric ceramic 6, and then activates the starting component 3. The longitudinal section of the movable guide column 42 is constructed as an inverted L-shape, and is provided with at least two short sides of the inverted L-shape connected, and the long sides are evenly distributed on the movable guide plate 43, and the starting component 3 is accommodated in the accommodating space enclosed by the movable guide column 42, the movable guide plate 43, and the hollow column 44; preferably, the movable guide column 42 is provided with three evenly distributed along the movable guide plate 43; wherein the starting component 3, the movable guide plate 43, and the hollow column 44 are coaxial.

Preferably, the starting assembly 3 further includes a medicine bin 33, the fire extinguishing agent column 31 and the starting medicine bag 32 are sealed in the medicine bin 33 to reduce the probability of moisture and improve the service life of the device; wherein, the medicine bin 33 is arranged in the movable part 4 and is coaxial with the movable part 4, the medicine bin 33 is preferably hollow cylindrical, and a plurality of nozzles 331 for aerosol spraying are opened on the top thereof, and sealed by a sticker 34 adapted to the top of the medicine bin 33. The piezoelectric ceramic 6 is located outside the medicine bin 33 to achieve closure under the push of the movable guide plate 43.

[0049] In a specific embodiment, see Figure 1-Figure 3 , Figure 6The shell 1 also includes a pressure rod 12 and a shell 13 located at the lower part of the pressure rod 12, and the lower part of the shell 13 is sealed by the base 11; the longitudinal section of the pressure rod 12 is constructed as an inverted L-shape, and at least two are provided, so that the short sides of the inverted L-shape are connected and the long sides are evenly distributed on the top surface of the shell 13; preferably, the pressure rods 12 are three; in order to improve the stability of the temperature detection element 2, the lower end surface of the short side of the inverted L-shape is provided with a clamping portion 14 to clamp the upper part of the temperature detection element 2; the shell 13 is a hollow structure to accommodate the trigger component and the starting component 3, the movable part 4, the elastic part 5, the piezoelectric ceramic 6, and the wire 7 are accommodated in the shell 13, and the upper part of the movable part 4 extends out of the upper end surface of the shell 13 and is connected to the lower part of the temperature detection element 2.

[0050] More specifically, see Figure 1 , Figure 6 In order to make the movable part 4 move in a directional manner, a guide sleeve 15 is provided in the shell 13 along its axial direction, so that the movable guide column 42 is inserted into the guide sleeve 15 and moves along its axial direction, and one movable guide column 42 corresponds to one guide sleeve 15; in order to extend the service life, a hollow cylinder 16 coaxial with the shell 13 is provided in the shell 13, and the guide sleeve 15 is tightly arranged outside the hollow cylinder 16 and arranged along its axial direction, and the upper part of the medicine chamber 33 is sleeved in the hollow cylinder 16, so that the aerosol formed after the starting component 3 is turned on moves in a directional manner through the hollow cylinder 16 to the outside of the shell 13 for fire extinguishing; more specifically, the top surface of the hollow cylinder 16 is connected to the top surface of the shell 13.

A recessed portion 112 is provided on the bracket 111 in a direction close to the center. When the medicine bin 33 is arranged on the bracket 111, a gap is formed between the medicine bin 33 and the base 11, and the wire 7 enters the bottom of the medicine bin 33 from the gap, and then enters the medicine bin 33 from the recessed portion 112 to connect with the starting medicine bag 32; in order to strengthen the strength of the device, reinforcing columns 17 are evenly distributed in the shell 13 along its axial direction.

[0052] The utility model is achieved in this way:

[0053] When the ambient temperature reaches the preset release temperature of the temperature detection element 2, the temperature detection element 2 bursts, and under the action of the elastic force of the elastic member 5, the three movable guide pillars 42 of the movable member 4 move axially through the three guide sleeves 15 in the shell 13. Since the elastic force of the elastic member 5 is greater than the elastic force of the piezoelectric ceramic 6, under the action of the elastic force of the elastic member 5, the upper end of the movable guide plate 43 applies upward pressure to the piezoelectric ceramic 6. When the piezoelectric ceramic 6 is closed, current is provided to the starting component 3 through the wire 7 to start the starting component 3. Subsequently, the fire extinguishing agent column 31 and the internal pressure of the agent chamber 33 increase instantly, and the aerosol generated by the fire extinguishing agent column 31 breaks through the sticker 34 to achieve the effect of spraying.

[0054] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
