DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] Reference Figure 1 An intelligent fire extinguishing warning device includes a housing 1 with a vertical through hole, that is, the horizontal cross-section of the housing 1 is circular or rectangular. The housing 1 is provided with fire extinguishing microcapsules 2, a control component 3 and a thermoelectric power generation module 4.

[0028] Thermoelectric power generation module 4 includes a P-type semiconductor 41 at the top of housing 1 and an N-type semiconductor 42 at the bottom. Together, these two components, along with housing 3, form a cavity. N-type semiconductor 42 is provided with a plurality of through-holes 43, which contain heat-dissolving hot-melt adhesive 44. The hot-melt adhesive 44 has a melting point of 95°C. Fire-extinguishing microcapsules 2 and control assembly 3 are located within the cavity.

[0029] The fire-extinguishing microcapsule 2 consists of a shell and a fire extinguishing agent disposed within the shell. The shell is made of a polymer or composite material, and the fire extinguishing agent is perfluorohexanone or another fluorine-based fire extinguishing agent. When heated, the perfluorohexanone fire extinguishing agent vaporizes and expands, bursting the shell and releasing the perfluorohexanone fire extinguishing agent into the fire space, thereby extinguishing the flames. The shell of the fire-extinguishing microcapsule has a rupture temperature of 100°C.

[0030] The control component 3 is provided with a control chip 31 and a communication module 32. The P-type semiconductor 41 and the N-type semiconductor 42 form a loop with the control component 3 via wires. The control chip 31 is used to control the conversion of electrical parameters and the transmission of data. The communication module 52 is a WiFi communication module or a 4G or 5G communication module.

[0031] When a fire occurs, the N-type semiconductor 42 of the thermoelectric power generation module 4 is heated. When the temperature difference between the N-type semiconductor 42 and the P-type semiconductor 41 exceeds 40°C, a current is generated to supply power to the control component 3. After powering on, the control component 3 converts and stores the electrical parameters generated by the thermoelectric power generation module 4 and transmits them to the backend terminal via the communication module 31. Simultaneously, when the fire temperature reaches the excitation temperature of the fire-extinguishing microcapsules 2, the microcapsules rupture and release the fire extinguishing agent.

[0032] Furthermore, the longitudinal cross-section of the housing 3 is arc-shaped. The arc-shaped structure can accommodate more fire-extinguishing microcapsules 2 under the housing 3 with a shorter width.

[0033] Furthermore, the fire extinguishing microcapsules 2 are fixed in the space enclosed by the housing 3 and the P-type semiconductor 41 and the N-type semiconductor 42 by means of a flame retardant hot melt adhesive, the melting temperature of which is 95°C.

[0034] Furthermore, a heat-absorbing layer is applied to the surface of the N-type semiconductor to accelerate its temperature rise, while a heat-insulating layer is applied to the surface of the P-type semiconductor to maintain its low temperature. The provision of these layers further accelerates the power-on time of control component 3, providing further assurance for the detection and handling of fire incidents.

[0035] Example 2:

[0036] This embodiment is a further improvement of the first embodiment, the difference is that Figure 2-4 , also includes a detection module 5.

[0037] The fire-extinguishing microcapsule 2 is secured to one side of the detection module 5 with glue. In this embodiment, the detection module 5 is a gravity sensing module, which is electrically connected to the control chip 31 of the control assembly 3. The gravity sensing module is secured below the P-type semiconductor, with the fire-extinguishing microcapsule 2 facing the N-type semiconductor 42. A fire-extinguishing microcapsule 2 of a certain weight is secured to the gravity sensing module, and its initial weight is recorded. When the fire-extinguishing microcapsule is released, the weight on the gravity sensing module decreases. The gravity sensing module transmits the reduced weight data to the control chip 31 and sends it via the communication module 32.

[0038] The control component 3 is positioned between the gravity sensing module and the P-type semiconductor 41. A conductive sheet 11 is embedded within the housing 3. Contacts 12 are located at both ends of the conductive sheet 11, penetrating the housing 3 and conducting between the P-type semiconductor 41 and the N-type semiconductor 42. These P-type semiconductor 41 and the N-type semiconductor 42 are connected to the control chip 31 of the control component 3 via wires, forming a closed circuit.

[0039] Furthermore, the conductive sheet 11 covers the entire interior of the housing 3, and the contact connector 32 is ring-shaped and fully conductively connected to the P-type semiconductor 41 and the N-type semiconductor 42. The provision of the fully contact conductive sheet 11 further ensures connectivity between the P-type semiconductor 41 and the N-type semiconductor 42, improving the electron transfer speed between the P-type semiconductor 41 and the N-type semiconductor 42, enabling the generation of a higher voltage current at a lower temperature, thereby better and more timely powering the control component 3.

[0040] Furthermore, the fire extinguishing microcapsules 2 are fixed on the gravity sensing module by flame retardant hot melt adhesive, and the melting temperature of the flame retardant hot melt adhesive is 100°C.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
