In the present embodiment, the medial surface of described base 6 is provided with and helically arranges (or, also can be inclined to set) two strip guide parts, the bottom sides surrounding of described valve rod 22 extends an annular slice body 221, the side correspondence of these plates 221 is provided with two adaptive with it auxiliary sections, and two guide parts are centrosymmetric, and two auxiliary sections are oppositely arranged, when described valve rod 22 moves downward, move along guide part and order about described base 6 and rotate in auxiliary section.Here, described guide part is specially guiding rib 61, and described auxiliary section is can the chute 222 of sliding sleeve outside this guiding rib 61.In addition, both also can exchange, that is, described guide part is gathering sill, and described auxiliary section is can the protuberance of sliding sleeve in gathering sill.The inside bottom of described base 6 is also provided with the limiting stand of an annular, carries out spacing to the downward storke of described valve rod 22.In addition, also the design of above-mentioned guide part and auxiliary section can be cancelled, and directly between base 6 with valve rod 22, coordinate the elastic component (this elastic component can adopt torsion spring to realize) being prefabricated with torsion, and when described valve rod 22 moves downward, this elastic component discharges its torsion and orders about described base 6 and rotates, thus drives described stirring pipe 7 to stir extinguishing chemical.
Preferred as one, described safety plug 3 is provided with the structure that fractures, and this respective outer side edges that fractures is in the position of described two jacks.Specifically, this structure that fractures is be located at multiple annular grooves 31 of described safety plug 3 side, and the plurality of annular groove 31 is arranged along the axially spaced-apart of safety plug 3.Except this, described in fracture structure also can for being located at multiple linear grooves of safety plug 3 side, and the plurality of linear groove is arranged along the axially spaced-apart of safety plug.One end of described safety plug 3 is also provided with a draw ring 32.Here, the design of the structure that fractures described in also can cancelling, but directly adopted by safety plug 3 strength more than 50 Ns can be made by disconnected easily broken material (such as engineering plastics), or, adopt easily broken material to make safety plug 3, fracture described in designing at this safety plug 3 structure simultaneously.
Preferred as one, the present invention also comprises warning device 8, this warning device 8 is specially Buzzing type warning device, it is connected with button starting switch 81, this warning device 8 is located at outside described valve body 21, on described pressure handle 4, correspondence is provided with a warning pressing lever 41, and when described pressure handle 4 is depressed, this warning pressing lever 41 touches and opens starting switch 81.Warning device 8 is outer is also provided with a protective cover 82, and specifically, this warning device 8 is installed on the medial surface of protective cover 82, and protective cover 82 is secured to the outside of described valve body 21.The upper side of this protective cover 82 and described carrying handle 5 are respectively equipped with a resigning hole 83 passed through for warning pressing lever 41.
Be combined with elastic component between the bottom of described valve rod 22 and the inside bottom of described base 6, the outside of described valve rod 22 is socketed with sealing gasket 23, the internal path of sealing pad 23 valve body 21 described in shutoff under the contact of elastic component.The present embodiment, elastic component preferably adopts spring 24 to realize.
The present invention also comprises Pressure gauge 9 and extinguishing chemical nozzle 10, and described valve body 21 is also provided with a pressure gauge connection, and Pressure gauge 9 is arranged at this pressure gauge connection; Extinguishing chemical nozzle 10 is secured to the extinguishing chemical outlet of described valve body 21.
A kind of hand fire extinguisher of the present invention, its using method and the course of work as follows:
Extract safety plug 3, pressure pressure handle 4, pressure handle 4 depresses valve rod 22, the elastic force making valve rod 22 overcome spring 24 moves downward, and open the internal path of valve body 21, simultaneously two chutes 222 of valve rod 22 move downward along two guiding ribs 61 of base 6, base 6 is impelled to rotate, thus drive stirring pipe 7 to rotate, screw mixing fin 72 then in stirring pipe 7 stirs the extinguishing chemical in extinguishing chemical cylindrical shell 1, the extinguishing chemical condensed in together is loosed off, and successively by stirring pipe 7 under the driving of the pressed gas prestored in extinguishing chemical cylindrical shell 1, base 6, the internal path of valve body 21, the extinguishing chemical spout of valve body 21, extinguishing chemical nozzle 10 ejects.
When pressure handle 4 is depressed, the warning pressing lever 41 on it also and then moves downward, and presses starting switch 81, makes warning device 8 continue to send buzzing chimes of doom.
When a fire, fire extinguishing personnel can make its inside because of static for a long time and the extinguishing chemical condensed in together looses off without the need to rocking hand fire extinguisher, enable fire extinguisher very first time when breaking out of fire spray a large amount of extinguishing chemical, and implement effectively fire extinguishing.On the other hand, the present invention also makes fire extinguishing personnel avoid rocking fire extinguisher when breaking out of fire, strives for the quality time for implementing effectively fire extinguishing.
When a fire, even if fire extinguishing personnel forget that unpluging safety plug 3 just presses pressure handle 4, also by disconnected safety plug 3 (as long as the strength more than 50 Ns can by this safety plug 3 disconnected), and can ensure that pressure handle 4 is indeformable, fire extinguisher is worked in time.
When non-breaking out of fire, and this hand fire extinguisher is misused when causing being in inefficacy or half failure state, warning device 8 starts, and continue to send buzzing chimes of doom, the prompting relevant personnel change fire extinguisher in time, avoid fire extinguisher to be in inefficacy or half failure state but not known to other people, thus cause the personnel of putting out a fire when a fire that this fire extinguisher cannot be utilized to put out a fire.
