Abstract
The present invention discloses an explosion-proof aerosol can. An internal circumference of a cover bottom forms a blocking end; a protruding rib is arranged on an internal edge at a top; the cover is provided with a cutting opening for lifting a nozzle on a suppressing disk; the blocking end is blocked in a can body; the suppressing disk is positioned inside the cover to lift; provided that the internal pressure of the can body exceeds a set threshold value, an upper cover of the can body is lifted upward and protruding which causes an upper end of the suppressing disk to be against the protruding rib on the internal edge of the cover, so the nozzle has the function of automatic pressure discharging in proper time. By using the explosion-proof aerosol can of the invention, various aerosol cans can be prevented causing the danger of explosion due to over-high internal pressure of can bodies, thus improving the problem that the existing aerosol can cannot provide the function of automatic pressure discharging when the internal pressure of the can body is too high.
Description
Technical field
The present invention relates to a kind of explosion-proof type spraying jug, is about pressing the technical field of tank body in having, referring to that especially its nozzle has in good time self-relieving effect when tank body loam cake rising protrusion, and then prevent to press in the tank body the too high explosion danger that causes.
Background technology
Structure by metal current material aerosol can is made up of valve group, loam cake, can body, bottom, and wherein the position of most fragile is a loam cake.
General aerosol can adopt as tin-plate make can ccontaining content the closed space; this content but disengages pressure because of being vulnerable to external temperature, moisture content or the like factor affecting; cause this closed space must bear aforementioned pressure; so can require the aerosol can material can possess the pressure that bears to a certain degree usually; but can bear pressure its limit is also arranged, (surpass 13kgf/cm as interior pressure in case surpass this pressure limit value
2) can cause loam cake protrusion, can body modification earlier, even more severe patient (surpasses 15kgf/cm as interior pressure
2) have an anxiety of splitting cruelly.
In view of the above,, directly do the pressure release action, still can avoid quick-fried jar basically, but problem is that general user is not for have the people who checks the aerosol can pressure condition on time by lower nozzle if when being found in loam cake and take place protruding phenomenon; On the contrary, even if be the people who checks the aerosol can pressure condition on time, this aerosol can internal pressure also may be pressed excessive blow-out in because of moment in non-check day.
For this reason, this case contriver accumulates various for many years New Product's Design and research and development experience, is the shortcoming in-depth study that excessive pressure release voluntarily causes explosion at above-mentioned known aerosol can internal pressure, and invention this case.
Summary of the invention
The object of the present invention is to provide a kind of aerosol can of giving when internal pressure is excessive, to have self-relieving explosion-proof type spraying jug.
For achieving the above object, the present invention takes following concrete technical scheme:
A kind of explosion-proof type spraying jug, it includes:
One tank body is to be made of loam cake, can body and bottom, and can body is adjacent to the loam cake place and is provided with edge clipping, and loam cake is convexly equipped with a valve group, the ccontaining valve pipe of loam cake central authorities;
One pressed discs is to form a spacer by disk body below, and the disk body periphery is convexly equipped with one and is the nozzle that is communicated with spacer inside air flue; And
One cap is to make above-mentioned pressed discs wherein ccontaining, and lid is provided with one can be for the groove of aforementioned nozzle lifting, and lid bottom inner peripheral forms the stopper end and in top hollow out one breach, lid top inner edge is provided with fin.
Above-mentioned explosion-proof type spraying jug, wherein, this disk body top is one to be the press section of depression.
Above-mentioned explosion-proof type spraying jug, wherein, this surface, press section forms several on-slip ribs.
Above-mentioned explosion-proof type spraying jug, wherein, this nozzle thickness is less than disk body thickness, and the two bottom height is identical.
Above-mentioned explosion-proof type spraying jug, wherein, this groove presents vertically relative on the space with breach.
Above-mentioned explosion-proof type spraying jug, wherein, this tank body can be the tin-plate material.
Above-mentioned explosion-proof type spraying jug, wherein, the fin of this lid top inner edge is arranged at the disk body top of this pressed discs.
Above-mentioned explosion-proof type spraying jug wherein, is provided with a scrobicular ring between this can body and the edge clipping.This
Advantage of the present invention is:
Compared to prior art, aerosol can of the present invention has can make the aerosol can internal pressure keep normally keeping the effectiveness of its content, and can be applied to the aerosol can that various materials make in view of the above and make it have the releasing pressure automatically function.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the present invention relates to a kind of explosion-proof type spraying jug, it includes: a tank body 1, be to constitute by loam cake 11, can body 12 and bottom 13, can body 12 contiguous what loam cakes 11 places are provided with edge clipping 121, and loam cake 11 is convexly equipped with a valve group 111, the ccontaining valve pipe 14 of loam cake 11 central authorities; One pressed discs 2 is to form a spacer 22 by disk body 21 belows, and disk body 21 peripheries are convexly equipped with one and are the nozzle 23 that is communicated with spacer 22 inner air flues 211; And a cap 3, make aforementioned pressed discs 2 wherein ccontaining, lid 31 is provided with one can be for the groove 311 of aforementioned nozzle 23 liftings, and lid 31 bottom inner peripherals form stopper ends 312 and in top hollow out one breach 313, lid 31 top inner edges are provided with fin 314;
These disk body 21 tops are one to be the press section 24 of depression, and these 24 surfaces, press section form several on-slip ribs 241;
These nozzle 23 thickness are less than disk body 21 thickness, and to make its two bottom be the design that flushes;
The fin 314 of these lid 31 top inner edges is to provide the disk body 21 top peripheries of above-mentioned pressed discs 2 to carry out resistancing action;
This groove 311 and breach 313 present vertically relative on the space, and this tank body 1 can be the tin-plate material or selects other materials.
As shown in Figure 4, the dotted line of the present invention in this figure is expression pressed discs 2,, the user do not drive valve pipe 14 (joining shown in Figure 1 in addition) decline as yet because of imposing application force, content in this moment what tank body 1 does not spray via nozzle 23: in case when this user desires to spray, only must impose application force in these pressed discs 2 tops, can cause this valve pipe 14 to descend slightly synchronously, on be set forth in the tank body 1 content promptly can by this nozzle 23 spray in outside, above-mentioned dropping distance is 2.5mm in the present invention, can make in this tank body 1 content by nozzle 23 ejections.
As shown in Figure 5, the present invention is the lid 31 bottom inner peripherals formation stopper ends 312 in cap 3, and be provided with fin 314 in the top inner edge, be provided with a groove 311 in this lid 31 in addition and can be beneficial to lifting for nozzle 23 location of pressed discs 2, this stopper end 312 is able to fastening on the scrobicular ring 122 of tank body 1, make this pressed discs 2 can be positioned lifting in this cap 3, if therefore if the interior pressure of this tank body 1 surpasses the critical value of setting (as interior pressure above 13kgf/cm
2), cause loam cake 11 risings of this tank body 1 to be protruded, and causing these pressed discs 2 upper ends can contact at the fin 314 of lid 31 top inner edges, disk body 21 can press down immediately and make above-mentioned valve pipe 14 (also joining shown in Figure 1 in addition) descend slightly, takes advantage of a situation to make this nozzle 23 have in good time self-relieving effect.
