Abstract

A fixed fire extinguisher apparatus comprising a housing (1), an activation controller (3), and an agent canister (2) arranged within the housing (1). The top end of the agent canister (2) extends to the top end of the housing (1), while a spout (4) of the agent canister (2) is exposedly arranged on the exterior of the housing (1). The agent canister (2) is fixedly connected to a sidewall of the housing (1). The activation controller (3) is arranged under the agent canister (2) within the housing (1). The fixed connection of the agent canister (2) to the sidewall conserves the space occupied by the bottom-portion structure of the agent canister (2). The arrangement of the activation controller (3) within the housing (1) allows for reduced overall size of the fire extinguisher apparatus, for reduced storage space, and for simplified wire connection to the agent canister (2).

Description

FIELD OF THE INVENTION The present invention relates to a fire fighting device, and in particular to a fixed fire extinguishing device. BACKGROUND OF THE INVENTION The occurrence of fires often causes significant losses to people's lives and property. Proper fire fighting equipment is essential to eliminate fires in the bud. The requirements for fire fighting equipment vary from site to site. In modern working and living environments, relatively small spaces such as transportation tools, electronic equipment, household appliances, kitchens, etc., ordinary fire extinguishing devices can effectively solve the fire extinguishing problem, but in a small space where the space is relatively small, such as 3~15 cubic meters. For applications such as power distribution cabinets and small unattended base stations, if existing fire-fighting devices are used, they often have low fire-extinguishing performance and may cause harm to human bodies or other items. Therefore, a small fixed automatic fire extinguishing device is indispensable. However, in the conventional fixed fire extinguishing device, the cartridge is easily shaken in the casing, which affects the fire extinguishing performance of the fire extinguishing device, and the casing is usually provided with the side plate independently fixed to the main body by screws, and the installation procedure is cumbersome. In addition, the starting controller is disposed on the outer wall of the casing, the wiring connection is complicated, and the volume of the entire device is increased, which affects the installation of the small space. SUMMARY OF THE INVENTION In order to solve the defects of the prior art fixed fire extinguishing device, the utility model provides a novel fixed fire extinguishing device with simple structure, convenient installation and improved fire extinguishing performance. The technical solution for solving the technical problem of the utility model is: a novel fixed fire extinguishing device, comprising a casing (1), a starting controller (3) and a cartridge (2) disposed in the casing (1); Wherein: the top end of the cartridge (2) extends to the top end of the casing (1) and the spout (4) of the cartridge (2) is exposed to the casing (1); the cartridge (2) and the shell The side wall of the body (1) is fixed; the starting controller (3) is disposed under the cartridge (2) in the casing (1); saving the space occupied by the bottom fixing structure of the cartridge (2), and The side wall connection fastens the cartridge (2) to prevent the possibility of deflagration of the medicament; and the starter controller (3) is built into the casing (1), so that the overall size of the fire extinguishing device is reduced, and the storage space is reduced. Moreover, the connection to the cartridge (2) is simplified. The bottom end of the cartridge (2) is provided with a square nut (6); the bottom end of the cartridge (2) and the bottom end of the side wall of the housing (1) are fitted and fixed by screws and nuts (6); Easy to install. The above casing (1) adopts an integrated arrangement; the manufacturing process and the assembly process are simplified. The casing (1) of the utility model is a die-cast aluminum profile; the die-casting aluminum profile has good heat dissipation effect, and the hollow between the cartridge (2) and the casing (1) is insulated by air, which is favorable for heat dissipation of the casing (1). The temperature of the outer wall of the casing (1) is not too high. The housing (1) is provided with a plurality of mounting holes (7) for easy fixing and assembly. The top end of the casing (1) is provided with a counterbore station (5) capable of clamping the top cover of the cartridge (2); so that the cartridge (2) is fixed from both ends, and the fixing effect is better. The above start controller (3) is started by an electric start mode. The fixed fire extinguishing device of the utility model can be used in multiple combinations, and is determined according to the application situation. The fixed fire extinguishing device of the present invention mainly has the following advantages: 1. The utility model extends through the top end of the medicine cartridge to the top end of the casing and the nozzle of the medicine cylinder is exposed outside the casing; the side wall of the medicine cylinder and the casing is solid The startup controller is disposed under the cartridge in the housing; the medicament is directly ejected after being ignited, and the fire extinguishing performance is good; the cartridge is fastened by the side wall connection, thereby saving the space occupied by the fixed structure at the bottom of the cartridge; The start controller is built into the casing, so that the overall size of the fire extinguishing device is reduced, the storage space is reduced, and the line connection with the cartridge is simplified. 2. The housing of the utility model adopts an integrated arrangement, which simplifies the processing technology and is convenient to install.

3. The utility model is fixed from both ends of the cartridge through the counterbore table at the top end of the casing and the low-end screw, so that the fixing is reliable, and there is a gap between the casing, which is favorable for heat insulation. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of the structure of the present invention; FIG. 2 is a cross-sectional view of FIG. 1; In the figure: 1-shell, 2-cartridge, 3-electric start controller, 4-spray, 5-sink table, 6-nut, 7-mounting hole. DETAILED DESCRIPTION OF THE INVENTION The present invention provides a fixed fire extinguishing device, which will now be described in connection with a preferred embodiment thereof. Referring to Figures 1 and 2, the fire extinguishing device is mainly composed of a casing 1, a cartridge 2 and a starter controller 3; wherein the cartridge 2 is disposed in the casing 1, and the top end of the cartridge 2 extends to the top of the casing 1. The nozzle 4 of the cartridge 2 is exposed to the housing 1; the internal structure thereof may adopt the structure in the prior art, or may be a structure improved in the prior art; the cartridge 2 in the embodiment includes the medicine. a barrel 2 body, a top cover disposed at the front end of the cartridge 2 body, and a horn nozzle, a honeycomb cooling layer, a coolant, a drug column, and an ignition head disposed at a junction of the drug column and the coolant; The top cover is further provided with a spout 4, and the center of the spout 4 is opposite to the center of the horn nozzle; the top cover extends to the casing 1 and the spout 4 is exposed at the top end of the casing 1 so that the hot aerosol gas emitted is not subjected to Any blockage, directly sprayed on the object of protection; the honeycomb cooling layer is a ceramic piece provided with holes, which can fix the coolant and prevent the coolant from falling out, and has physical cooling effect; the larger diameter end of the horn nozzle and the honeycomb cooling Layer connection, can be drained The aerosol gas is ejected from the spout 4, and generally, when the cartridge 2 is large in size, the horn nozzle is used when the medicinal column is far away from the spout 4.
